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.

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.

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.
