93-574: The Internet Engineering Task Force (IETF) originally defined IKE in November 1998 in a series of publications ( Request for Comments ) known as RFC 2407, RFC 2408 and RFC 2409: RFC   4306 updated IKE to version two (IKEv2) in December 2005. RFC   4718 clarified some open details in October 2006. RFC   5996 combined these two documents plus additional clarifications into

186-497: A Safe removal applet for removable storage devices. Windows 2000 SP4 added native USB 2.0 support, Wireless Zero Configuration support and SSE3 support. Windows 2000 is also the first Windows version to support hibernation at the operating system level (OS-controlled ACPI S4 sleep state) unlike Windows 98 which required special drivers from the hardware manufacturer or driver developer. A new capability designed to protect critical system files called Windows File Protection

279-452: A Windows Interface Source Environment partner. Microsoft issued the following statement: "Microsoft source code is both copyrighted and protected as a trade secret. As such, it is illegal to post it, make it available to others, download it or use it." Despite the warnings, the archive containing the leaked code spread widely on the file-sharing networks. On February 16, 2004, an exploit "allegedly discovered by an individual studying

372-416: A 2015 article "66% of VPN's [ sic ] are not in fact broken". IPsec VPN configurations which allow for negotiation of multiple configurations are subject to MITM -based downgrade attacks between the offered configurations, with both IKEv1 and IKEv2. This can be avoided by careful segregation of client systems onto multiple service access points with stricter configurations. Both versions of

465-399: A cache stored in a separate "DLLCACHE" directory, or from the original install media. Microsoft recognized that a serious error (a Blue Screen of Death or stop error) could cause problems for servers that needed to be constantly running and so provided a system setting that would allow the server to automatically reboot when a stop error occurred. Also included is an option to dump any of

558-510: A charter that describes its focus; and what it is expected to produce, and when. It is open to all who want to participate and holds discussions on an open mailing list . Working groups hold open sessions at IETF meetings, where the onsite registration fee in 2024 was between US$ 875 (early registration) and $ 1200 per person for the week. Significant discounts are available for students and remote participants. As working groups do not make decisions at IETF meetings, with all decisions taken later on

651-674: A cooperative agreement, No. NCR-8820945, wherein CNRI agreed to create and provide a "secretariat" for the "overall coordination, management and support of the work of the IAB, its various task forces and, particularly, the IETF". In 1992, CNRI supported the formation and early funding of the Internet Society, which took on the IETF as a fiscally sponsored project, along with the IAB, the IRTF, and

744-497: A file to be transparently referred from one file or directory location to another. Windows 2000 also introduces a Distributed Link Tracking service to ensure file shortcuts remain working even if the target is moved or renamed. The target object's unique identifier is stored in the shortcut file on NTFS 3.0 and Windows can use the Distributed Link Tracking service for tracking the targets of shortcuts, so that

837-470: A file with a bulk symmetric key (also known as the File Encryption Key, or FEK), which is used because it takes less time to encrypt and decrypt large amounts of data than if an asymmetric key cipher were used. The symmetric key used to encrypt the file is then encrypted with a public key associated with the user who encrypted the file, and this encrypted data is stored in the header of

930-403: A general facility for automatic negotiation of a well-known default case that is universally implemented. Consequently, both sides of an IKE had to exactly agree on the type of security association they wanted to create – option by option – or a connection could not be established. Further complications arose from the fact that in many implementations the debug output

1023-494: A name which referred to its projected release date. Windows 2000 Beta 3 was released in May 1999. Windows NT 5.0 Beta 1 was similar to Windows NT 4.0, including a very similarly themed logo. Windows NT 5.0 Beta 2 introduced a new 'mini' boot screen, and removed the 'dark space' theme in the logo. The Windows NT 5.0 betas had very long startup and shutdown sounds, though these were changed in the early Windows 2000 beta, but during Beta 3,

1116-514: A new piano -made startup and shutdown sounds were made, composed by Steven Ray Allen. It was featured in the final version as well as in Windows Me . The new login prompt from the final version made its first appearance in Beta 3 build 1946 (the first build of Beta 3). The new, updated icons (for My Computer , Recycle Bin etc.) first appeared in Beta 3 build 1964. The Windows 2000 boot screen in

1209-421: A performance diagnostic console, which displays graphs of system performance and configures data logs and alerts. It also contains a service configuration console, which allows users to view all installed services and to stop and start them, as well as configure what those services should do when the computer starts. CHKDSK has significant performance improvements. Windows 2000 comes with two utilities to edit

1302-588: A previewer can be enabled in previous versions of Windows with the Windows Desktop Update installed through the use of folder customization templates. The default file tooltip displays file title, author, subject and comments; this metadata may be read from a special NTFS stream, if the file is on an NTFS volume, or from an OLE structured storage stream, if the file is a structured storage document. All Microsoft Office documents since Office 4.0 make use of structured storage , so their metadata

1395-691: A simple command-line interface , used to check and repair the hard drive(s), repair boot information (including NTLDR ), replace corrupted system files with fresh copies from the CD, or enable/disable services and drivers for the next boot. The console can be accessed in either of the two ways: Windows 2000 introduced Windows Script Host 2.0 which included an expanded object model and support for logon and logoff scripts. The Windows 2000 Server family consists of Windows 2000 Server, Windows 2000 Advanced Server, Windows 2000 Small Business Server, and Windows 2000 Datacenter Server. All editions of Windows 2000 Server have

1488-483: A stack from one another. There are a number of implementations of IKEv2 and some of the companies dealing in IPsec certification and interoperability testing are starting to hold workshops for testing as well as updated certification requirements to deal with IKEv2 testing. The following open source implementations of IKEv2 are available: Leaked NSA presentations released in 2014 by Der Spiegel indicate that IKE

1581-540: Is a standards organization for the Internet and is responsible for the technical standards that make up the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors. The IETF was initially supported by the federal government of the United States but since 1993 has operated under

1674-817: Is a user who is authorized by a public key recovery certificate to decrypt files belonging to other users using a special private key . By default, local administrators are recovery agents however they can be customized using Group Policy . Windows 2000 introduced the Logical Disk Manager and the diskpart command line tool for dynamic storage . All versions of Windows 2000 support three types of dynamic disk volumes (along with basic disks): simple volumes , spanned volumes and striped volumes : In addition to these disk volumes, Windows 2000 Server, Windows 2000 Advanced Server, and Windows 2000 Datacenter Server support mirrored volumes and striped volumes with parity : With Windows 2000, Microsoft introduced

1767-421: Is also standardizing protocols for autonomic networking that enables networks to be self managing. It is a network of physical objects or things that are embedded with electronics, sensors, software and also enables objects to exchange data with operator, manufacturer and other connected devices. Several IETF working groups are developing protocols that are directly relevant to IoT . Its development provides

1860-700: Is available from these statistics. The IETF chairperson is selected by the NomCom process for a two-year renewable term. Before 1993, the IETF Chair was selected by the IAB. A list of the past and current chairs of the IETF: The IETF works on a broad range of networking technologies which provide foundation for the Internet's growth and evolution. It aims to improve the efficiency in management of networks as they grow in size and complexity. The IETF

1953-551: Is being exploited in an unknown manner to decrypt IPsec traffic, as is ISAKMP. The researchers who discovered the Logjam attack state that breaking a 1024-bit Diffie–Hellman group would break 66% of VPN servers, 18% of the top million HTTPS domains, and 26% of SSH servers, which the researchers claim is consistent with the leaks. This claim was refuted in 2015 by both Eyal Ronen and Adi Shamir in their paper "Critical Review of Imperfect Forward Secrecy" and by Paul Wouters of Libreswan in

2046-564: Is displayable in the Windows 2000 Explorer default tooltip . File shortcuts can also store comments which are displayed as a tooltip when the mouse hovers over the shortcut. The shell introduces extensibility support through metadata handlers, icon overlay handlers and column handlers in Explorer Details view . The right pane of Windows 2000 Explorer, which usually just lists files and folders, can also be customized. For example,

2139-743: Is done—for example, some use virtual devices, others take a slice out of the firewall, etc. IKEv1 consists of two phases: phase 1 and phase 2. IKE phase one's purpose is to establish a secure authenticated communication channel by using the Diffie–Hellman key exchange algorithm to generate a shared secret key to encrypt further IKE communications. This negotiation results in one single bi-directional ISAKMP security association. The authentication can be performed using either pre-shared key (shared secret), signatures, or public key encryption. Phase 1 operates in either Main Mode or Aggressive Mode. Main Mode protects

2232-493: Is improved over Windows NT 4.0 with a number of new assistive technologies , and Microsoft increased support for different languages and locale information. The Windows 2000 Server family has additional features, most notably the introduction of Active Directory , which in the years following became a widely used directory service in business environments. Four editions of Windows 2000 have been released: Professional , Server , Advanced Server , and Datacenter Server ;

2325-581: Is integrated into Windows 2000 Explorer, unlike the separate search dialog found in all previous Explorer versions. The Indexing Service has also been integrated into the operating system and the search pane built into Explorer allows searching files indexed by its database. Microsoft released the version 3.0 of NTFS (sometimes incorrectly called "NTFS 5" in relation to the kernel version number) as part of Windows 2000; this introduced disk quotas (provided by QuotaAdvisor), file-system-level encryption , sparse files and reparse points . Sparse files allow for

2418-598: Is on implementing code that will improve standards in terms of quality and interoperability. The details of IETF operations have changed considerably as the organization has grown, but the basic mechanism remains publication of proposed specifications, development based on the proposals, review and independent testing by participants, and republication as a revised proposal, a draft proposal, or eventually as an Internet Standard. IETF standards are developed in an open, all-inclusive process in which any interested individual can participate. All IETF documents are freely available over

2511-452: Is on the IETF meetings page. The IETF strives to hold its meetings near where most of the IETF volunteers are located. IETF meetings are held three times a year, with one meeting each in Asia, Europe and North America. An occasional exploratory meeting is held outside of those regions in place of one of the other regions. The IETF also organizes hackathons during the IETF meetings. The focus

2604-569: Is overseen by an area director (AD), with most areas having two ADs. The ADs are responsible for appointing working group chairs. The area directors, together with the IETF Chair, form the Internet Engineering Steering Group (IESG), which is responsible for the overall operation of the IETF. The Internet Architecture Board (IAB) oversees the IETF's external relationships. The IAB provides long-range technical direction for Internet development. The IAB also manages

2697-561: Is responsible for day-to-day management of the IETF. It receives appeals of the decisions of the working groups, and the IESG makes the decision to progress documents in the standards track . The chair of the IESG is the area director of the general area, who also serves as the overall IETF chair. Members of the IESG include the two directors, sometimes three, of each of the following areas: Liaison and ex officio members include: The Gateway Algorithms and Data Structures (GADS) Task Force

2790-497: Is the direct successor to Windows NT 4.0 , and was released to manufacturing on December 15, 1999, officially released to retail on February 17, 2000 for all versions, and on September 26, 2000 for Windows 2000 Datacenter Server. It was Microsoft's primary business-oriented operating system until the introduction of Windows XP Professional in 2001. Windows 2000 introduces NTFS 3.0, Encrypting File System , and basic and dynamic disk storage. Support for people with disabilities

2883-649: Is the first Windows NT release to include Active Desktop , first introduced as a part of Internet Explorer 4.0 (specifically Windows Desktop Update ), and only pre-installed in Windows 98 by that time. It allowed users to customize the way folders look and behave by using HTML templates, having the file extension HTT . This feature was abused by computer viruses that employed malicious scripts, Java applets, or ActiveX controls in folder template files as their infection vector. Two such viruses are VBS/Roor-C and VBS.Redlof.a. The "Web-style" folders view, with

2976-547: Is the first system to integrate these two programs into a single utility, adopting the REGEDIT behavior with the additional NT features. The System File Checker (SFC) also comes with Windows 2000. It is a command line utility that scans system files and verifies whether they were signed by Microsoft and works in conjunction with the Windows File Protection mechanism. It can also repopulate and repair all

3069-450: Is then given to the IPsec stack. For instance, this could be an AES key, information identifying the IP endpoints and ports that are to be protected, as well as what type of IPsec tunnel has been created. The IPsec stack, in turn, intercepts the relevant IP packets if and where appropriate and performs encryption/decryption as required. Implementations vary on how the interception of the packets

3162-746: The DirectX API , commonly used by game developers on Windows 98 . The last version of DirectX that was released for Windows 2000 was DirectX 9.0c (Shader Model 3.0), which shipped with Windows XP Service Pack 2. Microsoft published quarterly updates to DirectX 9.0c through the February 2010 release after which support was dropped in the June 2010 SDK. These updates contain bug fixes to the core runtime and some additional libraries such as D3DX , XAudio 2 , XInput and Managed DirectX components. The majority of games written for versions of DirectX 9.0c (up to

3255-635: The Internet Research Task Force (IRTF), with which the IETF has a number of cross-group relations. A nominating committee (NomCom) of ten randomly chosen volunteers who participate regularly at meetings, a non-voting chair and 4-5 liaisons, is vested with the power to appoint, reappoint, and remove members of the IESG, IAB, IETF Trust and the IETF LLC. To date, no one has been removed by a NomCom, although several people have resigned their positions, requiring replacements. In 1993

3348-882: The Microsoft Management Console (MMC), UDF support, the Encrypting File System (EFS), Logical Disk Manager , Image Color Management 2.0, support for PostScript 3 -based printers, OpenType (.OTF) and Type 1 PostScript (.PFB) font support (including a new font— Palatino Linotype —to showcase some OpenType features ), the Data protection API (DPAPI), an LDAP / Active Directory -enabled Address Book , usability enhancements and multi-language and locale support. Windows 2000 also introduced USB device class drivers for USB printers, Mass storage class devices , and improved FireWire SBP-2 support for printers and scanners, along with

3441-427: The Windows registry , REGEDIT.EXE and REGEDT32.EXE . REGEDIT has been directly ported from Windows 98 , and therefore does not support editing registry permissions. REGEDT32 has the older multiple document interface (MDI) and can edit registry permissions in the same manner that Windows NT's REGEDT32 program could. REGEDIT has a left-side tree view of the Windows registry , lists all loaded hives and represents

3534-565: The kernel that processes the actual IP packets. User-space daemons have easy access to mass storage containing configuration information, such as the IPsec endpoint addresses, keys and certificates, as required. Kernel modules, on the other hand, can process packets efficiently and with minimum overhead—which is important for performance reasons. The IKE protocol uses UDP packets, usually on port 500, and generally requires 4–6 packets with 2–3 round trips to create an ISAKMP security association (SA) on both sides. The negotiated key material

3627-510: The DFS root, the user is really looking at a DFS link and the DFS server transparently redirects them to the correct file server and share. A DFS root can only exist on a Windows 2000 version that is part of the server family, and only one DFS root can exist on that server. There can be two ways of implementing a DFS namespace on Windows 2000: either through a standalone DFS root or a domain-based DFS root. Standalone DFS allows for only DFS roots on

3720-674: The February 2010 release) can therefore run on Windows 2000. Windows 2000 included the same games as Windows NT 4.0 did: FreeCell , Minesweeper , Pinball , and Solitaire . Windows 2000 introduced the Microsoft Management Console (MMC), which is used to create, save, and open administrative tools. Each of these is called a console , and most allow an administrator to administer other Windows 2000 computers from one centralised computer. Each console can contain one or many specific administrative tools, called snap-ins . These can be either standalone (with one function), or an extension (adding functions to an existing snap-in). In order to provide

3813-591: The IETF changed from an activity supported by the US federal government to an independent, international activity associated with the Internet Society , a US-based 501(c)(3) organization . In 2018 the Internet Society created a subsidiary, the IETF Administration LLC, to be the corporate, legal and financial home for the IETF. IETF activities are funded by meeting fees, meeting sponsors and by

3999-620: The ISOC's board of directors. In 2018, ISOC established The IETF Administration LLC, a separate LLC to handle the administration of the IETF. In 2019, the LLC issued a call for proposals to provide secretariat services to the IETF. The first IETF meeting was attended by 21 US federal government-funded researchers on 16 January 1986. It was a continuation of the work of the earlier GADS Task Force. Representatives from non-governmental entities (such as gateway vendors ) were invited to attend starting with

4092-644: The Internet Society via its organizational membership and the proceeds of the Public Interest Registry . In December 2005, the IETF Trust was established to manage the copyrighted materials produced by the IETF. The Internet Engineering Steering Group (IESG) is a body composed of the Internet Engineering Task Force (IETF) chair and area directors. It provides the final technical review of Internet standards and

4185-481: The Internet Standards process, the Internet Standards or their technical content". In 1998, CNRI established Foretec Seminars, Inc. (Foretec), a for-profit subsidiary to take over providing secretariat services to the IETF. Foretec provided these services until at least 2004. By 2013, Foretec was dissolved. In 2003, IETF's RFC  3677 described IETFs role in appointing three board members to

4278-588: The Internet and can be reproduced at will. Multiple, working, useful, interoperable implementations are the chief requirement before an IETF proposed specification can become a standard. Most specifications are focused on single protocols rather than tightly interlocked systems. This has allowed the protocols to be used in many different systems, and its standards are routinely re-used by bodies which create full-fledged architectures (e.g. 3GPP IMS ). Because it relies on volunteers and uses "rough consensus and running code" as its touchstone, results can be slow whenever

4371-666: The KLIPS or XFRM/NETKEY kernel-based IPsec stacks. XFRM/NETKEY is the Linux native IPsec implementation available as of version 2.6. The Berkeley Software Distributions also implements IPsec, IKE daemon via the OpenBSD Cryptographic Framework (OCF), which makes supporting cryptographic accelerators much easier. OCF has recently been ported to Linux. A number of network equipment vendors have created their own IKE daemons (and IPsec implementations), or license

4464-704: The OEM channel and then were superseded by the final versions of Server 2003. Windows 2000 introduced many of the new features of Windows 98 and 98 SE into the NT line, such as the Windows Desktop Update , Internet Explorer 5 ( Internet Explorer 6 , which followed in 2001, is also available for Windows 2000), Outlook Express , NetMeeting , FAT32 support, SSE and SSE2 support, Windows Driver Model , Internet Connection Sharing , Windows Media Player 6.4, WebDAV support etc. Certain new features are common across all editions of Windows 2000, among them NTFS 3.0,

4557-829: The Windows 9x accessibility features for people with visual and auditory impairments and other disabilities into the NT-line of operating systems. These included: Additionally, Windows 2000 introduced the following new accessibility features: Windows 2000 introduced the Multilingual User Interface (MUI). Besides English , Windows 2000 incorporates support for Arabic , Armenian , Baltic , Central European, Cyrillic , Georgian , Greek , Hebrew , Indic , Japanese , Korean , simplified Chinese , Thai , traditional Chinese , Turkic , Vietnamese and Western European languages. It also has support for many different locales. Windows 2000 included version 7.0 of

4650-425: The Windows equivalent of a log file , a system information utility, a backup utility , Task Scheduler and management consoles to view open shared folders and shared folder sessions, configure and manage COM+ applications, configure Group Policy , manage all the local users and user groups, and a device manager . It contains Disk Management and Removable Storage snap-ins, a disk defragmenter as well as

4743-511: The ability of internet applications to send data over the Internet. There are some well-established transport protocols such as TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) which are continuously getting extended and refined to meet the needs of the global Internet. Windows 2000 Windows 2000 is a major release of the Windows NT operating system developed by Microsoft and oriented towards businesses. It

4836-540: The ability to control what snap-ins can be seen in a console, the MMC allows consoles to be created in author mode or user mode . Author mode allows snap-ins to be added, new windows to be created, all portions of the console tree to be displayed and consoles to be saved. User mode allows consoles to be distributed with restrictions applied. User mode consoles can grant full access to the user for any change, or they can grant limited access, preventing users from adding snapins to

4929-957: The ability to launch multiple programs without closing the menu by holding down the SHIFT key. A Re-sort button forces the entire Start Menu to be sorted by name. The Taskbar introduces support for balloon notifications which can also be used by application developers. Windows 2000 Explorer introduces customizable Windows Explorer toolbars, auto-complete in Windows Explorer address bar and Run box, advanced file type association features, displaying comments in shortcuts as tooltips, extensible columns in Details view (IColumnProvider interface), icon overlays, integrated search pane in Windows Explorer, sort by name function for menus, and Places bar in common dialogs for Open and Save . Windows Explorer has been enhanced in several ways in Windows 2000. It

5022-418: The auspices of the Internet Society , a non-profit organization with local chapters around the world. There is no membership in the IETF. Anyone can participate by signing up to a working group mailing list, or registering for an IETF meeting. The IETF operates in a bottom-up task creation mode, largely driven by working groups. Each working group normally has appointed two co-chairs (occasionally three);

5115-729: The console though they can view multiple windows in a console. Alternatively users can be granted limited access, preventing them from adding to the console and stopping them from viewing multiple windows in a single console. The main tools that come with Windows 2000 can be found in the Computer Management console (in Administrative Tools in the Control Panel). This contains the Event Viewer —a means of viewing system or application-related events and

5208-509: The contents of the system folders aren't displayed by default, instead showing in the right pane a warning to the user that modifying the contents of the system folders could harm their computer. It's possible to define additional Explorer panes by using DIV elements in folder template files. This degree of customizability is new to Windows 2000; neither Windows 98 nor the Desktop Update could provide it. The new DHTML-based search pane

5301-485: The efficient storage of data sets that are very large yet contain many areas that only have zeros. Reparse points allow the object manager to reset a file namespace lookup and let file system drivers implement changed functionality in a transparent manner. Reparse points are used to implement volume mount points , junctions , Hierarchical Storage Management , Native Structured Storage and Single Instance Storage . Volume mount points and directory junctions allow for

5394-404: The encrypted file. To decrypt the file, the file system uses the private key of the user to decrypt the symmetric key stored in the file header. It then uses the symmetric key to decrypt the file. Because this is done at the file system level, it is transparent to the user. For a user losing access to their key, support for recovery agents that can decrypt files is built into EFS. A Recovery Agent

5487-470: The event a deficit occurs, CNRI has agreed to contribute up to USD$ 102,000 to offset it." In 1993, Cerf continued to support the formation of ISOC while working for CNRI, and the role of ISOC in "the official procedures for creating and documenting Internet Standards" was codified in the IETF's RFC   1602 . In 1995, IETF's RFC  2031 describes ISOC's role in the IETF as being purely administrative, and ISOC as having "no influence whatsoever on

5580-626: The files in the Dllcache folder. The Recovery Console is run from outside the installed copy of Windows to perform maintenance tasks that can neither be run from within it nor feasibly be run from another computer or copy of Windows 2000. It is usually used to recover the system from problems that cause booting to fail, which would render other tools useless, like Safe Mode or Last Known Good Configuration, or chkdsk . It includes commands like fixmbr , which are not present in MS-DOS. It has

5673-655: The final version first appeared in Beta 3 build 1983. Windows 2000 did not have an actual codename because, according to Dave Thompson of Windows NT team, " Jim Allchin didn't like codenames". , although Windows 2000 Service Pack 1 was codenamed "Asteroid". During development, builds for the Alpha architecture were compiled, but the project was abandoned in the final stages of development (between RC1 and RC2 ) after Compaq announced they had dropped support for Windows NT on Alpha. From here, Microsoft issued three release candidates between July and November 1999, and finally released

In order to improve performance on servers running Windows 2000, Microsoft gave administrators the choice of optimizing

5859-473: The first officially released 64-bit version of Windows was Windows XP 64-Bit Edition , released alongside the 32-bit editions of Windows XP on October 25, 2001, followed by the server versions Windows Datacenter Server Limited Edition and later Windows Advanced Server Limited Edition , which were based on the pre-release Windows Server 2003 (then known as Windows .NET Server ) codebase. These editions were released in 2002, were shortly available through

5952-490: The following services and features built in: The Server editions include more features and components, including the Microsoft Distributed File System (DFS), Active Directory support and fault-tolerant storage. The Distributed File System (DFS) allows shares in multiple different locations to be logically grouped under one folder, or DFS root . When users try to access a network share off

6045-404: The fourth IETF meeting in October 1986. Since that time all IETF meetings have been open to the public. Initially, the IETF met quarterly, but from 1991, it has been meeting three times a year. The initial meetings were very small, with fewer than 35 people in attendance at each of the first five meetings. The maximum attendance during the first 13 meetings was only 120 attendees. This occurred at

6138-588: The identity of the peers and the hash of the shared key by encrypting them; Aggressive Mode does not. During IKE phase two, the IKE peers use the secure channel established in Phase 1 to negotiate Security Associations on behalf of other services like IPsec . The negotiation results in a minimum of two unidirectional security associations (one inbound and one outbound). Phase 2 operates only in Quick Mode. Originally, IKE had numerous configuration options but lacked

6231-465: The kernel PnP Manager along with the Power Manager are two significant subsystems added in Windows 2000. Windows 2000 introduced version 3 print drivers (user mode printer drivers) based on Unidrv , which made it easier for printer manufacturers to write device drivers for printers. Generic support for 5-button mice is also included as standard and installing IntelliPoint allows reassigning

6324-400: The latter was both released to manufacturing and launched months after the other editions. While each edition of Windows 2000 is targeted at a different market, they share a core set of features, including many system utilities such as the Microsoft Management Console and standard system administration applications. Microsoft marketed Windows 2000 as the most secure Windows version ever at

6417-458: The leaked source code" for certain versions of Microsoft Internet Explorer was reported. On April 15, 2015, GitHub took down a repository containing a copy of the Windows NT 4.0 source code that originated from the leak. Microsoft planned to release in 2000 a version of Windows 2000, specially codenamed "Janus", which would run on 64-bit Intel Itanium microprocessors . However,

6510-524: The left Explorer pane displaying details for the object currently selected, is turned on by default in Windows 2000. For certain file types, such as pictures and media files, the preview is also displayed in the left pane. Until the dedicated interactive preview pane appeared in Windows Vista , Windows 2000 had been the only Windows release to feature an interactive media player as the previewer for sound and video files, enabled by default. However, such

6603-423: The number of volunteers is either too small to make progress, or so large as to make consensus difficult, or when volunteers lack the necessary expertise. For protocols like SMTP , which is used to transport e-mail for a user community in the many hundreds of millions, there is also considerable resistance to any change that is not fully backward compatible , except for IPv6 . Work within the IETF on ways to improve

6696-432: The operating system to partners on December 12, 1999, followed by manufacturing three days later on December 15. The public could buy the full version of Windows 2000 on February 17, 2000. Three days before this event, which Microsoft advertised as "a standard in reliability," a leaked memo from Microsoft reported on by Mary Jo Foley revealed that Windows 2000 had "over 63,000 potential known defects." After Foley's article

6789-738: The operating system's memory and processor usage patterns for background services or for applications. Windows 2000 also introduced core system administration and management features, such as the Windows Installer , Windows Management Instrumentation and Event Tracing for Windows (ETW) into the operating system. The most notable improvement from Windows NT 4.0 is the addition of Plug and Play with full ACPI and Windows Driver Model support. Similar to Windows 9x , Windows 2000 supports automatic recognition of installed hardware, hardware resource allocation, loading of appropriate drivers, PnP APIs and device notification events. The addition of

6882-419: The organization of annual INET meetings. Gross continued to serve as IETF chair throughout this transition. Cerf, Kahn, and Lyman Chapin announced the formation of ISOC as "a professional society to facilitate, support, and promote the evolution and growth of the Internet as a global research communications infrastructure". At the first board meeting of the Internet Society, Cerf, representing CNRI, offered, "In

6975-485: The programmable buttons. Windows 98 lacked generic support. Driver Verifier was introduced to stress test and catch device driver bugs. Windows 2000 introduces layered windows that allow for transparency, translucency and various transition effects like shadows, gradient fills and alpha-blended GUI elements to top-level windows. Menus support a new Fade transition effect. The Start menu in Windows 2000 introduces personalized menus , expandable special folders and

7068-414: The release "our tests show the successor to Windows NT 4.0 is everything we hoped it would be. Of course, it isn't perfect either." Wired News later described the results of the February launch as "lackluster." Novell criticized Microsoft's Active Directory , the new directory service architecture, as less scalable or reliable than its own Novell Directory Services (NDS) alternative. Windows 2000

7161-611: The shortcut file may be silently updated if the target moves, even to another hard drive. The Encrypting File System (EFS) introduced strong file system -level encryption to Windows. It allows any folder or drive on an NTFS volume to be encrypted transparently by the user. EFS works together with the EFS service, Microsoft's CryptoAPI and the EFS File System Runtime Library (FSRTL). To date, its encryption has not been compromised. EFS works by encrypting

7254-525: The speed of the standards-making process is ongoing but, because the number of volunteers with opinions on it is very great, consensus on improvements has been slow to develop. The IETF cooperates with the W3C , ISO / IEC , ITU , and other standards bodies. Statistics are available that show who the top contributors by RFC publication are. While the IETF only allows for participation by individuals, and not by corporations or governments, sponsorship information

7347-420: The three components of a value (its name, type, and data) as separate columns of a table. REGEDT32 has a left-side tree view, but each hive has its own window, so the tree displays only keys and it represents values as a list of strings. REGEDIT supports right-clicking of entries in a tree view to adjust properties and other settings. REGEDT32 requires all actions to be performed from the top menu bar . Windows XP

7440-502: The time; however, it became the target of a number of high-profile virus attacks such as Code Red and Nimda . For ten years after its release, it continued to receive patches for security vulnerabilities nearly every month until reaching the end of support on July 13, 2010, the same day that support ended for Windows XP SP2 . Windows 2000 and Windows 2000 Server were succeeded by Windows XP and Windows Server 2003 , released in 2001 and 2003, respectively. Although unreleased, it

7533-487: The twelfth meeting, held during January 1989. These meetings have grown in both participation and scope a great deal since the early 1990s; it had a maximum attendance of 2810 at the December 2000 IETF held in San Diego, California . Attendance declined with industry restructuring during the early 2000s, and is currently around 1200. The locations for IETF meetings vary greatly. A list of past and future meeting locations

7626-510: The updated IKEv2, published in September 2010. A later update upgraded the document from Proposed Standard to Internet Standard , published as RFC   7296 in October 2014. The parent organization of the IETF, the Internet Society (ISOC), has maintained the copyrights of these standards as freely available to the Internet community. Most IPsec implementations consist of an IKE daemon that runs in user space and an IPsec stack in

7719-490: The working group mailing list , meeting attendance is not required for contributors. Rough consensus is the primary basis for decision making. There are no formal voting procedures. Each working group is intended to complete work on its topic and then disband. In some cases, the working group will instead have its charter updated to take on new tasks as appropriate. The working groups are grouped into areas by subject matter ( see § Steering group , below ). Each area

7812-573: Was Mike Corrigan, who was then the technical program manager for the Defense Data Network (DDN). Also in 1986, after leaving DARPA, Robert E. Kahn founded the Corporation for National Research Initiatives (CNRI), which began providing administrative support to the IETF. In 1987, Corrigan was succeeded as IETF chair by Phill Gross. Effective March 1, 1989, but providing support dating back to late 1988, CNRI and NSF entered into

7905-589: Was described in Appendix A of RFC 4306 in 2005. The following issues were addressed: The IETF ipsecme working group has standardized a number of extensions, with the goal of modernizing the IKEv2 protocol and adapting it better to high volume, production environments. These extensions include: IKE is supported as part of the IPsec implementation in Windows 2000 , Windows XP , Windows Server 2003 , Windows Vista and Windows Server 2008 . The ISAKMP/IKE implementation

7998-636: Was developed on Alpha in alpha, beta, and release candidate versions. Its successor, Windows XP , only supports x86 , x64 and Itanium processors. Both the Original Xbox and the Xbox 360 use a modified version of Windows 2000 as their system software . Windows 2000, originally named Windows NT 5.0, is a continuation of the Microsoft Windows NT family of operating systems, replacing Windows NT 4.0 . Chairman and CEO Bill Gates

8091-472: Was difficult to interpret, if there was any facility to produce diagnostic output at all. The IKE specifications were open to a significant degree of interpretation, bordering on design faults ( Dead Peer Detection being a case in point), giving rise to different IKE implementations not being able to create an agreed-upon security association at all for many combinations of options, however correctly configured they might appear at either end. The IKEv2 protocol

8184-490: Was initially planned to replace both Windows 98 and Windows NT 4.0 . However, this would be changed later, as an updated version of Windows 98 called Windows 98 Second Edition was released in 1999. On or shortly before February 12, 2004, "portions of the Microsoft Windows 2000 and Windows NT 4.0 source code were illegally made available on the Internet." The source of the leak was later traced to Mainsoft ,

8277-497: Was introduced. This protects critical Windows system files by preventing programs other than Microsoft's operating system update mechanisms such as the Package Installer , Windows Installer and other update components from modifying them. The System File Checker utility provides users the ability to perform a manual scan of the integrity of all protected system files, and optionally repair them, either by restoring from

8370-537: Was jointly developed by Cisco and Microsoft. Microsoft Windows 7 and Windows Server 2008 R2 partially support IKEv2 ( RFC  7296 ) as well as MOBIKE ( RFC  4555 ) through the VPN Reconnect feature (also known as Agile VPN ). There are several open source implementations of IPsec with associated IKE capabilities. On Linux , Libreswan , Openswan and strongSwan implementations provide an IKE daemon which can configure (i.e., establish SAs) to

8463-479: Was originally "pretty confident" Windows NT 5.0 would ship in the first half of 1998, revealing that the first set of beta builds had been shipped in early 1997; these builds were identical to Windows NT 4.0. The first official beta was released in September 1997, followed by Beta 2 in August 1998. On October 27, 1998, Microsoft announced that the name of the final version of the operating system would be Windows 2000,

8556-467: Was published, she claimed that Microsoft blacklisted her for a considerable time. However, Abraham Silberschatz et al. claim in their computer science textbook that "Windows 2000 was the most reliable, stable operating system Microsoft had ever shipped to that point. Much of this reliability came from maturity in the source code, extensive stress testing of the system, and automatic detection of many serious errors in drivers." InformationWeek summarized

8649-646: Was the precursor to the IETF. Its chairman was David L. Mills of the University of Delaware . In January 1986, the Internet Activities Board (IAB; now called the Internet Architecture Board) decided to divide GADS into two entities: an Internet Architecture (INARC) Task Force chaired by Mills to pursue research goals, and the IETF to handle nearer-term engineering and technology transfer issues. The first IETF chair
