Mainstream support ended on April 12, Extended support ended on April 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  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  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 Powershell. This console program gave administrators the ability to manage all network devices, whether physical or virtual, from a single location. To support the use of containers, VM systems were enhanced to interact with Docker and to support encryption for Hyper-V. Additionally, the release included Server Core. The Windows Server release only had Standard and Datacenter editions, and it did not have a follow-up R2 version.
The most current Windows Server version is Windows Server It was released in October and included several important new features to meet growing networking requirements:. Some companies find it difficult to upgrade each time a new version of Windows Server is released. Products in LTSC remain supported for a full ten years. This covers five years of support as part of the purchase, and another five years with a support contract extension. The R2 versions are the exception, since those are supplied as a free upgrade to customers who have the original version of the release.
For example, upgrading to Windows R2 was free for customers who had Windows Server Several versions of Windows Server are still in active use today: R2, R2, , and Not all companies need or want to wait ten years to upgrade.
For companies needing more frequent updates and innovations, Microsoft introduced another purchasing model, the Semi-Annual Channel SAC , in SAC Windows Server products have new releases every six months, with support contracts that only last eighteen months.
Another difference is while the LTSC editions use the standard Windows naming convention, the SAC editions are named based on the year and month of the release. Using Windows Server in the cloud frees up companies from the need to host the software on their on-premises machines. Instead, they can use a remote infrastructure such as Microsoft Azure cloud servers, offered on a subscription basis. You can also use other cloud providers, such as Google Cloud, for Windows Server.
Having third-party options gives you more flexibility in choosing which plan works best for your company. For companies wanting a hybrid approach, where only some of the server activity is in the cloud, this is also supported with the latest versions of Windows Server. Whatever approach you take will give you seamless service. This is necessary to track any problems with the hardware and to ensure all the server connections are operating correctly.
This is true for both the cloud and on-premises versions of the system. It allows you to:. This means that if you are installing Windows Server R2 on a physical box you are probably using it as a host machine for Hyper-V to run your virtual machines in your network. Those free virtual machines licenses are called the virtualization rights. This is where the reasoning for Datacenter comes into play. With Standard edition, you got 2 virtualization rights but with Windows Server R2 Data Center edition you get unlimited virtualization rights.
In this case, unlimited means as many virtual machines as your hardware platform can support. Why would anyone buy Standard edition with its 2 virtualization rights when you could buy Data Center edition and get unlimited rights? Customers who had already bought Windows Server were allowed access to this new version for free. All Windows Server sales from the release of this version, were actually Windows Server R2. The improvements to the Windows Server system that appeared with R2 focused on security issues.
User authentication was based on Active Directory and still is to this date. However, Microsoft developed an extra feature for this authentication system and that was bundled into R2. This new feature was the Active Directory Federation Services. This enabled them to be accessed with users that were verified through AD without directly including the authentication procedures of that software into AD.
The R2 package also made it possible to set security policies for groups of machines through the Security Configuration Wizard. Other R2 improvements included better data compression for files and transfers and replication procedures for multi-site WANs.
The next version of Windows Server took three years to get ready and it included another enhancement to Active Directory. The company also made some fundamental changes to how network services interacted with the software support features of the operating system. If system administrators already have Hyper-V installed why go to the expense of bringing in a rival VM system? These were useful system administration tools that enabled administrators to get better control over the activities of the server.
Server Core was an increasingly important product of Microsoft. It was the bare version of the Windows Server software and it allowed command-line access. It can be run without the familiar GUI Desktop of the Windows environment and appealed more to systems administrators who were more comfortable with the command line environments that they used on Unix and Linux.
First made available in , Windows Server R2 is still in use today. Most of the changes that distinguish this from the original Windows Server were technical and occurred in the underlying supporting services. Up to this point, Windows Server products were based on Windows Vista.
Windows Server R2 has a Windows 7 heart. So, that takes the program execution system up to a bit environment. This version of Windows Server saw some more changes in Active Directory to improve group policy implementation and a few new services appeared. BranchCache and DirectAccess also appeared in this version of Windows Server to improve access to the server from users at remote locations.
By , Microsoft was going all out to win in the Cloud , so it added features to Windows Server to enable better interaction with off-site services. All of the improvements to the Windows Server system in this version focused on getting the integrated Hyper-V into shape to make Cloud resources as easy to integrate into onsite delivery as local hosts.
The storage system, mediated by Hyper-V was also updated in this version. The Hyper-V virtual switch and Hyper-V Replica were included in this release to enhance the uptake of hybrid network strategies.
The Essentials edition was aimed at small businesses. This revision to Windows Server was released in The composition of the operating system saw the use of PowerShell extended even further. Microsoft continued its aim to provide better server functions onsite that provided the capability to integrate cloud services.
This involved rewriting security systems and network services. Virtualization and storage systems were also overhauled and Web services were enhanced. The storage features that were enhanced in this upgrade included replication for distributed files and improved access for file sharing.
