Windows Server R2 - Wikipedia.Kaspersky Security 10 for Windows Server
Mainstream support ended on April 12, Extended support ended on April 12, [11] [12]. Windows Server is the second version of Windows Server operating system produced by Microsoft. It is part of the Windows NT family of operating systems and was released on April 24, An updated version , Windows Server R2, was released to manufacturing on December 6, Windows Server is based on the consumer operating system, Windows XP.
Windows Server is the follow-up to Windows Server, incorporating compatibility and other features from Windows XP. Unlike Windows , Windows Server 's default installation has none of the server components enabled, to reduce the attack surface of new machines. Windows Server includes compatibility modes to allow older applications to run with greater stability. It was made more compatible with Windows NT 4.
Windows Server brought in enhanced Active Directory compatibility and better deployment support to ease the transition from Windows NT 4. Windows Server is the first server edition of Windows to support the IA64 and x64 architectures. The product went through several name changes during the course of development. When first announced in , it was known by its codename "Whistler Server"; it was named "Windows Server" for a brief time in mid, followed by "Windows.
NET Server" and "Windows. NET Server ". After Microsoft chose to focus the ". NET" branding on the. Windows Server was the first Microsoft Windows version which was thoroughly subjected to semi-automated testing for bugs with a software system called PREfast [17] developed by computer scientist Amitabh Srivastava at Microsoft Research.
Microsoft co-founder Bill Gates stated that Windows Server was Microsoft's "most rigorously tested software to date. Microsoft used Windows Server 's kernel in the development of Windows Vista.
Windows Server comes in a number of editions, each targeted towards a particular size and type of business. NET technology. Domain controller and Terminal Services functionality are not included on Web Edition. However, Remote Desktop for Administration is available. Only 10 concurrent file-sharing connections are allowed at any moment. NET Framework version 2. When using it for storage or as a back-end with another remote server as the front-end, CALs may still be required.
Microsoft Windows Server Standard is aimed towards small to medium-sized businesses. Standard Edition supports file and printer sharing, offers secure Internet connectivity, and allows centralized desktop application deployment. A specialized variant for the x64 architecture was released in April Windows Server Enterprise is aimed towards medium to large businesses.
It also provides the ability to hot-add supported hardware. Windows Server Enterprise is also the required edition to issue custom certificate templates. Windows Server Datacenter is designed [25] for infrastructures demanding high security and reliability. Windows Server is available for IA, Itanium, and x64 processors. It supports a maximum of 32 physical processors on IA platform or 64 physical processors on x64 and IA hardware.
The Datacenter edition, like the Enterprise edition, supports 8-node clustering. Clustering increases availability and fault tolerance of server installations by distributing and replicating the service among many servers. This edition supports clustering with each cluster having its own dedicated storage, or with all cluster nodes connected to a common SAN.
Windows Compute Cluster Server CCS , released in June , is designed for high-end applications that require high performance computing clusters. It is designed to be deployed on numerous computers to be clustered together to achieve supercomputing speeds. Each Compute Cluster Server network comprises at least one controlling head node and subordinate processing nodes that carry out most of the work.
It ties nodes together with a powerful inter-process communication mechanism which can be complex because of communications between hundreds or even thousands of processors working in parallel. The application programming interface consists of over functions. A job launcher enables users to execute jobs to be executed in the computing cluster.
Windows Storage Server , a part of the Windows Server series, is a specialized server operating system for network-attached storage NAS. Launched in at Storage Decisions in Chicago, it is optimized for use in file and print sharing and also in storage area network SAN scenarios.
It is only available through Original equipment manufacturers OEMs. Windows Storage Server NAS equipment can be headless , which means that they are without any monitors, keyboards or mice, and are administered remotely. Such devices are plugged into any existing IP network and the storage capacity is available to all users. Multiple such NAS servers can be clustered to appear as a single device, which allows responsibility for serving clients to be shared in such a way that if one server fails then other servers can take over often termed a failover which also improves fault-tolerance.
Windows Storage Server can also be used to create a Storage Area Network , in which the data is transferred in terms of chunks rather than files, thus providing more granularity to the data that can be transferred. This provides higher performance to database and transaction processing applications. Single instance storage SIS scans storage volumes for duplicate files, and moves the duplicate files to the common SIS store. The file on the volume is replaced with a link to the file.
Windows Storage Server R2 provides an index-based, full-text search based on the indexing engine already built into Windows server. Windows Storage Server can be promoted to function as a domain controller; however, this edition is not licensed to run directory services. It can be joined to an existing domain as a member server.
Windows Small Business Server SBS is a software suite which includes Windows Server and additional technologies aimed at providing a small business with a complete technology solution.
SBS has the following design limitations, mainly affecting Active Directory: [30]. Windows Home Server was announced on January 7, , at the Consumer Electronics Show by Bill Gates and is intended to be a solution for homes with multiple connected PCs to offer file sharing, automated backups, and remote access. Intended use was for building firewall, VPN caching servers and similar appliances. Availability of the original version ended May 28, Availability of R2 ended March 5, End of extended support was July 14, all variants except Storage Server [9] , and End of Licence was May 28, R2 and original.
All variants continued to receive Critical security updates until the end of extended support: [37]. While many features of the bit variant of Windows XP were brought over into Windows XP Professional x64 Edition, other limitations imposed by constraints such as only supporting bit drivers, and support for bit programs being dropped led to incompatibilities with the bit Windows XP editions available.
Among the improvements are many of the same updates that were provided to Windows XP users with Service Pack 2. Features that are added with Service Pack 1 include:. A full list of updates is available in the Microsoft Knowledge Base. Service Pack 2 for Windows Server was released on March 13, This was followed by build , known as Beta 2 Refresh. The final build is Microsoft has described Service Pack 2 as a "standard" service pack release containing previously released security updates, hotfixes, and reliability and performance improvements.
Service Pack 2 also adds Windows Server Scalable Networking Pack SNP , [48] which allows hardware acceleration for processing network packets, thereby enabling faster throughput.
Windows Server R2 is an updated release of Windows Server , which contains a copy of Windows Server SP1 on one CD and a host of optionally installed new features on another disc, similar to Microsoft Plus! New features of Windows Server R2 include: [51]. On July 13, , Windows Server 's mainstream support expired and the extended support phase began.
During the extended support phase, Microsoft continued to provide security updates; however, free technical support, warranty claims, and design changes are no longer being offered. Although Windows Server is unsupported, Microsoft released an emergency security patch in May for the OS as well as other unsupported versions of Windows including Windows Vista and Windows 7 RTM without a service pack , to address a vulnerability that was being leveraged by the WannaCry ransomware attack.
Anonymous users from managed to compile the Windows Server source code, as well as a Twitter user who posted videos of the process on YouTube proving that the code was genuine, [57] but was removed from the platform on copyright grounds by Microsoft.
The leak was incomplete as it was missing the Winlogon source code and some other components. Microsoft issued a statement stating that it was investigating the leaks. From Wikipedia, the free encyclopedia.

Windows Server R2 | Microsoft Evaluation Center - INTRODUCTION
Windows NT introduced its own driver model, the Windows NT driver model, and is incompatible with older driver frameworks. Windows 3. This decision caused tension between Microsoft and IBM and the collaboration ultimately fell apart. Like VMS, [23] Windows NT's kernel mode code distinguishes between the "kernel", whose primary purpose is to implement processor- and architecture-dependent functions, and the "executive". This was designed as a modified microkernel , as the Windows NT kernel was influenced by the Mach microkernel developed by Richard Rashid at Carnegie Mellon University, [25] but does not meet all of the criteria of a pure microkernel.
Both the kernel and the executive are linked together into the single loaded module ntoskrnl. Routines from each are directly accessible, as for example from kernel-mode device drivers. Windows NT was one of the earliest operating systems to use Unicode internally. Windows NT 4. The first release was given version number 3. Also the Novell IPX protocol was apparently licensed only to 3. The NT version number is not now generally used for marketing purposes, but is still used internally, and said to reflect the degree of changes to the core of the operating system.
Starting with Windows 8. If an application is not manifested for Windows 8. Assembly language is avoided where possible because it would impede portability. In order to prevent Intel x86 -specific code from slipping into the operating system by developers used to developing on x86 chips, Windows NT 3.
Both systems were designed internally at Microsoft. Only two of the Windows NT 4. All of the other ports done by third parties Motorola, Intergraph, etc. Microsoft demonstrated a preliminary version of Windows version 6. According to Microsoft, it is a common misconception that the Xbox and Xbox use a modified Windows kernel. In reality, the Xbox operating system was built from scratch but implements a subset of Windows APIs.
Windows 11 is the first non-server version of Windows NT to not support bit platforms. The minimum hardware specification required to run each release of the professional workstation version of Windows NT has been fairly slow-moving until the 6. From Wikipedia, the free encyclopedia. Microsoft computer operating system family. This article is about the family of operating system versions by Microsoft.

On June 25, , Microsoft released Windows 98 code-named Memphis , three years after the release of Windows 95 , two years after the release of Windows NT 4. USB support in Windows 98 is marketed as a vast improvement over Windows The release continued the controversial inclusion of the Internet Explorer browser with the operating system that started with Windows 95 OEM Service Release 1.
The action eventually led to the filing of the United States v. Microsoft case, dealing with the question of whether Microsoft was introducing unfair practices into the market in an effort to eliminate competition from other companies such as Netscape. In , Microsoft released Windows 98 Second Edition, an interim release. One of the more notable new features was the addition of Internet Connection Sharing , a form of network address translation , allowing several machines on a LAN Local Area Network to share a single Internet connection.
Hardware support through device drivers was increased and this version shipped with Internet Explorer 5. Many minor problems that existed in the first edition were fixed making it, according to many, the most stable release of the Windows 9x family.
Mainstream support for Windows 98 and 98 SE ended on June 30, , and ended extended support on July 11, It has the version number Windows NT 5. Windows has had four official service packs. It was successfully deployed both on the server and the workstation markets.
Amongst Windows 's most significant new features was Active Directory , a near-complete replacement of the NT 4.
Terminal Services , previously only available as a separate edition of NT 4, was expanded to all server versions. A number of features from Windows 98 were incorporated also, such as an improved Device Manager, Windows Media Player , and a revised DirectX that made it possible for the first time for many modern games to work on the NT kernel.
Windows is also the last NT-kernel Windows operating system to lack product activation. While Windows upgrades were available for Windows 95 and Windows 98, it was not intended for home users. It was the last DOS-based operating system from Microsoft. Windows Me introduced a new multimedia-editing application called Windows Movie Maker , came standard with Internet Explorer 5. System Restore was a notable feature that would continue to thrive in all later versions of Windows.
Windows Me was conceived as a quick one-year project that served as a stopgap release between Windows 98 and Windows XP. Many of the new features were available from the Windows Update site as updates for older Windows versions System Restore and Windows Movie Maker were exceptions.
Windows Me was criticized for stability issues, as well as for lacking real mode DOS support, to the point of being referred to as the "Mistake Edition. The initial release was met with considerable criticism , particularly in the area of security , leading to the release of three major Service Packs. Service Pack 2 provided significant improvements and encouraged widespread adoption of XP among both home and business users.
Windows XP was one of Microsoft's longest-running flagship operating systems, beginning with the public release on October 25, , for at least 5 years, and ending on January 30, , when it was succeeded by Windows Vista. On April 25, , Microsoft launched Windows Server , a notable update to Windows Server encompassing many new security features, a new "Manage Your Server " wizard that simplifies configuring a machine for specific roles, and improved performance. It is based on the Windows NT 5.
A few services not essential for server environments are disabled by default for stability reasons, most noticeable are the "Windows Audio" and "Themes" services; users have to enable them manually to get sound or the " Luna " look as per Windows XP.
The hardware acceleration for display is also turned off by default, users have to turn the acceleration level up themselves if they trust the display card driver. Among the new features are a number of management features for branch offices, file serving, printing and company-wide identity integration.
Windows Server R2, an update of Windows Server , was released to manufacturing on December 6, The other CD adds many optionally installable features for Windows Server The R2 update was released for all x86 and x64 versions, except Windows Server R2 Enterprise Edition, which was not released for Itanium.
It is designed to use the expanded bit memory address space provided by the x86—64 architecture. Windows XP Professional x64 Edition is based on the Windows Server codebase, with the server features removed and client features added. It is only available to Software Assurance customers. The aim of WinFLP is to give companies a viable upgrade option for older PCs that are running Windows 95, 98, and Me that will be supported with patches and updates for the next several years.
Most user applications will typically be run on a remote machine using Terminal Services or Citrix. While being visually the same as Windows XP, it has some differences. For example, if the screen has been set to 16 bit colors, the Windows recycle bin icon and some XP bit icons will show. Paint and some games like Solitaire aren't present too.
Windows Home Server code-named Q, Quattro is a server product based on Windows Server , designed for consumer use. The system was announced on January 7, , by Bill Gates. Windows Home Server can be configured and monitored using a console program that can be installed on a client PC.
Such features as Media Sharing, local and remote drive backup and file duplication are all listed as features. Windows Vista was released on November 30, , to business customers—consumer versions followed on January 30, Windows Vista intended to have enhanced security by introducing a new restricted user mode called User Account Control , replacing the "administrator-by-default" philosophy of Windows XP.
Vista was the target of much criticism and negative press, and in general was not well regarded, this was seen as leading to the relatively swift release of Windows 7. One major difference between Vista and earlier versions of Windows, Windows 95 and later, was that the original start button was replaced with the Windows icon in a circle called the Start Orb. Windows Vista had the version number NT 6.
During its lifetime, Windows Vista had two service packs. Windows Vista shipped in six editions : [36]. All editions except Starter edition were available in both bit and bit versions. The biggest advantage of the bit version was breaking the 4 gigabyte memory barrier, which bit computers cannot fully access.
Windows Server built on the technological and security advances first introduced with Windows Vista, and was significantly more modular than its predecessor, Windows Server Windows 7 was released to manufacturing on July 22, , and reached general retail availability on October 22, The interface was renewed with a bigger taskbar and some improvements in the searching system and the Start menu. Windows 7 met with positive reviews, which said the OS was faster and easier to use than Windows Vista.
Windows 7 shipped in six editions : [40]. In some countries in the European Union , there were other editions that lacked some features such as Windows Media Player, Windows Media Center and Internet Explorer—these editions were called names such as "Windows 7 N. All editions, except the Starter edition, were available in both bit and bit versions.
Unlike the corresponding Vista editions, the Professional and Enterprise editions were supersets of the Home Premium edition. Windows Server R2 shipped in bit versions x64 and Itanium only.
WinTPC was available for software assurance customers and relied on cloud computing in a business network. Wireless operation is supported since WinTPC has full wireless stack integration, but wireless operation may not be as good as the operation on a wired connection. Windows Home Server code named 'Vail' [43] was released on April 6, WHS only supports x hardware.
Microsoft decided to discontinue Windows Home Server on July 5, while including its features into Windows Server Essentials. Windows 8 went on sale to the public on October 26, Windows 8 features a redesigned user interface, designed to make it easier for touchscreen users to use Windows.
The interface introduced an updated Start menu known as the Start screen, and a new full-screen application platform. The desktop interface is also present for running windowed applications, although Windows RT will not run any desktop applications not included in the system.
On the Building Windows 8 blog, it was announced that a computer running Windows 8 can boot up much faster than Windows 7.
Windows 8. So far, neither has had any service packs yet, although many consider Windows 8. However, Windows 8. Windows 10 was unveiled on September 30, , as the successor for Windows 8, and was released on July 29, A number of new features like Cortana , the Microsoft Edge web browser, the ability to view Windows Store apps as a window instead of fullscreen, the return of the Start menu, virtual desktops, revamped core apps, Continuum, and a unified Settings app were all features debuted in Windows The system was announced as a service OS that would receive constant performance and stability updates.
Unlike Windows 8, Windows 10 received mostly positive reviews, praising improvements of stability and practicality than its predecessor, however, it received some criticsm due to mandatory update installation, privacy concerns and advertising-supported software tactics. Although Microsoft claimed Windows 10 would be the last Windows version, eventually a new major release, Windows 11, was announced in That made Windows 10 last longer as Microsoft's flagship operating system than any other version of Windows, beginning with the public release on July 29, , for six years, and ending on October 5, , when Windows 11 was released.
Until late , Windows 10 had received twelve main updates. Windows Server is a release of the Microsoft Windows Server operating system that was unveiled on September 30, Windows Server is a release of the Microsoft Windows Server operating system that was announced on March 20, The first Windows Insider preview version was released on the same day. It was released for general availability on October 2, Windows Server is based on the Windows 10 October Update codebase.
On October 6, , distribution of Windows version build was paused while Microsoft investigated an issue with user data being deleted during an in-place upgrade. It affected systems where a user profile folder e. Documents, Music or Pictures had been moved to another location, but data was left in the original location. As Windows Server is based on the Windows version codebase, it too was removed from distribution at the time, but was re-released on November 13, The software product life cycle for Server was reset in accordance with the new release date.
Windows Server is a release of the Microsoft Windows Server operating system which is based on the Windows 10 November Update codebase. Windows 11 is the next generation release of Windows NT, and the successor to Windows Codenamed "Sun Valley", it was unveiled on June 24, , and was released on October 5, According to Microsoft, Windows 11 will be released for newer PCs first and then the initial release will continue till mid Windows 11 revamps the GUI and brings modern code, thus making it much faster than Windows It is also noted that Windows 11 updates are significantly compressed, so the updates are downloaded faster.
Also, Windows 11 does not show signs of the 'Installing Updates' screen while installing updates during 'Update and Restart' phase, thus finishing updates within 5 minutes. The system incorporates a renewed interface called "Mica", which includes translucent backgrounds, rounded edges and color combinations. The taskbar and the Start Menu have been redesigned and for the first time it is possible to place the icons in the center of the bar. The MSN widget panel, the Microsoft Store, and the file browser, among other applications, have also been redesigned.
It is expected that it will soon include compatibility with Android applications. You cannot upgrade domain controllers that run Windows Server or bit versions of Windows Server To replace them, install domain controllers that run a later version of Windows Server in the domain, and then remove the domain controllers that Windows Server Note that you cannot convert a domain controller that runs an evaluation version of Windows Server directly to a retail version.
Instead, install an additional domain controller on a server that runs a retail version and remove AD DS from the domain controller that runs on the evaluation version. Due to a known issue, you cannot upgrade a domain controller that runs a Server Core installation of Windows Server R2 to a Server Core installation of Windows Server The upgrade will hang on a solid black screen late in the upgrade process. Rebooting such DCs exposes an option in boot. An additional reboot triggers the automatic rollback to the previous operating system version.
Until a solution is available, it is recommended that you install a new domain controller running a Server Core installation of Windows Server instead of in-place upgrading an existing domain controller that runs a Server Core installation of Windows Server R2.
For more information, see KB article Windows Server requires a Windows Server forest functional level. That is, before you can add a domain controller that runs Windows Server to an existing Active Directory forest, the forest functional level must be Windows Server or higher. This means that domain controllers that run Windows Server R2, Windows Server , or Windows Server can operate in the same forest, but domain controllers that run Windows Server are not supported and will block installation of a domain controller that runs Windows Server If the forest contains domain controllers running Windows Server or later but the forest functional level is still Windows , the installation is also blocked.
Windows domain controllers must be removed prior to adding Windows Server domain controllers to your forest.
In this case, consider the following workflow:. The new Windows Server domain functional level enables one new feature: the KDC support for claims, compound authentication, and Kerberos armoring KDC administrative template policy has two settings Always provide claims and Fail unarmored authentication requests that require Windows Server domain functional level.
The Windows Server forest functional level does not provide any new features, but it ensures that any new domain created in the forest will automatically operate at the Windows Server domain functional level.
The Windows Server domain functional level does not provide other new features beyond KDC support for claims, compound authentication, and Kerberos armoring. But it ensures that any domain controller in the domain runs Windows Server After you set the forest functional level to a certain value, you cannot roll back or lower the forest functional level, with the following exceptions: after you raise the forest functional level to Windows Server , you can lower it to Windows Server R2.
If the forest functional level is set to Windows Server R2 , it cannot be rolled back, for example, to Windows Server After you set the domain functional level to a certain value, you cannot roll back or lower the domain functional level, with the following exceptions: when you raise the domain functional level to Windows Server R2 or Windows Server , and if the forest functional level is Windows Server or lower, you have the option of rolling the domain functional level back to Windows Server or Windows Server R2.
If the domain functional level is set to Windows Server R2 , it cannot be rolled back, for example, to Windows Server Beyond functional levels, a domain controller that runs Windows Server provides additional features that are not available on a domain controller that runs an earlier version of Windows Server.
For example, a domain controller that runs Windows Server can be used for virtual domain controller cloning, whereas a domain controller that runs an earlier version of Windows Server cannot. But virtual domain controller cloning and virtual domain controller safeguards in Windows Server do not have any functional level requirements. Microsoft Exchange Server requires a forest functional level of Windows server or higher.
AD DS cannot be installed on a server that also runs the following server roles or role services:. Though they are not operations master roles, another change in AD DS installation is that DNS server role and the global catalog are installed by default on all domain controllers that run Windows Server Improvements in AD DS beginning in Windows Server enable safer virtualization of domain controllers and the ability to clone domain controllers.
Cloning domain controllers in turn enables rapid deployment of additional domain controllers in a new domain and other benefits. The following table covers common Active Directory-integrated Microsoft applications. The table covers what versions of Windows Server that the applications can be installed on and whether the introduction of Windows Server DCs affects application compatibility. Configuration Manager Configuration Manager Service Pack 1: Microsoft will add the following operating systems to our client support matrix with the release of Service Pack 1: - Windows 8 Pro - Windows 8 Enterprise - Windows Server Standard - Windows Server Datacenter All site server roles - including site servers, SMS providers, and management points - can be deployed to servers with the following operating system editions: - Windows Server Standard - Windows Server Datacenter Microsoft Endpoint Configuration Manager current branch Supported operating systems for Configuration Manager site system servers.
It cannot be run on a Server Core installation. It can be run on virtual servers.
