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.

Service Pack for Windows & Windows Server R2? – Windows Forum

 

This article describes some issues that occur on a Windows Server R2-based domain controller. A hotfix is available to resolve these issues.

The hotfix has a prerequisite. Assume that you have a domain controller that is running Windows Server R2, you may encounter one of the following issues. Issue 1: Domain join You have a new computer, and you want to join it to a domain of the forest. The same computer host name is already used in another domain. In this situation, the domain join operation reports success.

After you click OK , you will see the following dialog box. The erased strings are the old and the new primary suffix of the computer: The error message resembles the following:.

After restart, the computer will report itself as a domain member, but interactive logon with a domain account will fail, and you will receive the following error message:. The security database on the server does not have a computer account for this workstation trust relationship. Issue 2: Intra-forest migration If you perform an intra-forest user migration that has service principal name SPN or user principal name UPN defined or intra-forest computer migration, the migration fails because the account still exists in the global catalog as the object is introduced in the target domain that has these attributes populated.

If the object was saved in the new domain, a duplicate SPN would be created. You add an SPN to the object that used to have another user or computer account in the forest. When you now try to restore the deleted account, the action fails because of the duplicate SPN. It successfully prevents duplicate SPN and UPN when they are driven through administrative tools without requiring the tool to perform a uniqueness check itself. In the issues that were described in this article, it prevents administrative tasks where the effect is not obvious.

In some cases, you can delete the objects that block your action so that the action is successful. Such a preparation change might not be possible in all cases. Therefore, Microsoft has developed an update that enables controlling the domain controller behavior.

This update applies to Windows Server R2-based domain controllers. You can also install this update on member servers that are candidate for promotion to a domain controller in the future. With this update, Microsoft provides a forest level switch to turn off or turn on uniqueness check through the dSHeuristics attribute.

The following are the supported dSHeuristics values:. For disabling UPN uniqueness check, set the 21st character of dSHeuristics to “1” For disabling SPN uniqueness check, set the 21st character of dSHeuristics to “2” For detailed information about how to modify dSHeuristic, see 6.

We recommend that you set the value back to 0 when you know problematic changes are not occurring any longer. This can be the case especially for intra-forest migrations. Important If you install a language pack after you install this hotfix, you must reinstall this hotfix.
