Windows Server 2008 is the most recent release of Microsoft Windows's server line of operating systems. Released on February 27, 2008, it is the successor to Windows Server 2003, released nearly five years earlier. Like Windows Vista, Windows Server 2008 is built on the Windows NT 6.0 kernel.
History
It was known as Windows Server Codename "Longhorn" until May 16, 2007, when Microsoft chairman Bill Gates announced its official title (Windows Server 200 during his keynote address at WinHEC.[1]

Beta 1 was released on July 27, 2005, Beta 2 was announced and released on May 23, 2006 at WinHEC 2006 and Beta 3 was released publicly on April 25, 2007.[2] Release Candidate 0 was released to the general public on September 24, 2007[3] and Release Candidate 1 was released to the general public on December 5, 2007. Windows Server 2008 was released to manufacturing on February 4, 2008 and officially launched on February 27, 2008.[4]

Features
See also: Features new to Windows Vista
Windows Server 2008 is built from the same code base as Windows Vista; therefore, it shares much of the same architecture and functionality. Since the code base is common, it automatically comes with most of the technical, security, management and administrative features new to Windows Vista such as the rewritten networking stack (native IPv6, native wireless, speed and security improvements); improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features such as BitLocker and ASLR; improved Windows Firewall with secure default configuration; .NET Framework 3.0 technologies, specifically Windows Communication Foundation, Microsoft Message Queuing and Windows Workflow Foundation; and the core kernel, memory and file system improvements. Processors and memory devices are modelled as Plug and Play devices, to allow hot-plugging of these devices. This allows the system resources to be partitioned dynamically using Dynamic Hardware Partitioning; each partition having its own memory, processor and I/O host bridge devices independent of other partitions.[5]


Server Core
Windows Server 2008 includes a variation of installation called a Server Core. Server Core is a significantly scaled-back installation where no Windows Explorer shell is installed. All configuration and maintenance is done entirely through command line interface windows, or by connecting to the machine remotely using Microsoft Management Console. However, Notepad and some control panel applets, such as Regional Settings, are available.

Server Core also does not include the .NET Framework, Internet Explorer or many other features not related to core server features. A Server Core machine can be configured for several basic roles: Domain controller/Active Directory Domain Services, ADLDS (ADAM), DNS Server, DHCP Server, file server, print server, Windows Media Server, IIS 7 web server and Hyper-V virtual server. This last role is projected to be available at most 180 days after release of Windows Server 2008; a beta version was shipped with the released product. Server Core can also be used to create a cluster with high availability using Failover Clustering or Network Load Balancing.


Active Directory roles
Active Directory is expanded with identity, certificate, and rights management services. Active Directory until Windows Server 2003 allowed network administrators to centrally manage connected computers, to set policies for groups of users, and to centrally deploy new applications to multiple computers. This role of Active Directory is being renamed as Active Directory Domain Services (ADDS).[6] A number of other additional services are being introduced, including Active Directory Federation Services (ADFS), Active Directory Lightweight Directory Services (ADLDS), (formerly Active Directory Application Mode, or ADAM), Active Directory Certificate Services (ADCS), and Active Directory Rights Management Services (ADRMS). Identity and certificate services allow administrators to manage user accounts and the digital certificates that allow them to access certain services and systems. Federation management services enable enterprises to share credentials with trusted partners and customers, allowing a consultant to use his company user name and password to log in on a client's network. Identity Integration Feature Pack is included as Active Directory Metadirectory Services. Each of these services represents a server role.


Terminal Services
Windows Server 2008 features major upgrades to Terminal Services. Terminal Services now supports Remote Desktop Protocol 6.0. The most notable improvement is the ability to share a single application over a Remote Desktop connection, instead of the entire desktop. This feature is called Terminal Services RemoteApp. Other features new to Terminal Services include Terminal Services Gateway and Terminal Services Web Access (full web interface). With Terminal Services Gateway, authorized computers are able to connect securely to a Terminal Server or Remote Desktop from the Internet using RDP via HTTPS without implementing a VPN session first. Additional ports do not need to be opened in the firewall; RDP is tunneled through HTTPS. Terminal Services Web Access enables administrators to provide access to the Terminal Services Sessions via a Web interface. TS Web Access comes with an adjustable Webpart for IIS and Sharepoint, which advertises the possible applications and connections to the user. Using TS Gateway and TS RemoteApp, the whole communication is via HTTP(S) and the remote applications appear transparent to the user as if they are running locally. Multiple applications run in the same session to ensure that there is no need for additional licenses per user. Terminal Services Easy Print does not require administrators to install any printer drivers on the server, but guarantees successful client printer redirection and availability of all printer UI and properties for use in remote sessions. Terminal Services sessions are created in parallel, instead of a serial operation - the new session model can initiate at least four sessions in parallel, or more if a server has more than four processors.
Windows PowerShell

Windows Server 2008 is the first Windows operating system to ship with Windows PowerShell, Microsoft's new extensible command line shell and task-based scripting technology.[7] PowerShell is based on object-oriented programming and version 2.0 of the Microsoft .NET Framework and includes more than 120 system administration utilities, consistent syntax and naming conventions, and built-in capabilities to work with common management data such as the Windows Registry, certificate store, or Windows Management Instrumentation. PowerShell's scripting language was specifically designed for IT administration, and can be used in place of cmd.exe and Windows Script Host.


Self-healing NTFS
In previous Windows versions, if the operating system detected corruption in the file system of an NTFS volume, it marked the volume "dirty"; to correct errors on the volume, it had to be taken offline. With self-healing NTFS, an NTFS worker thread is spawned in the background which performs a localized fix-up of damaged data structures, with only the corrupted files/folders remaining unavailable without locking out the entire volume and needing the server to be taken down.[8]

Hyper-V

Hyper-V architectureMain article: Hyper-V
Hyper-V is a hypervisor-based virtualization system, forming a core part of Microsoft's virtualization strategy. It virtualizes servers on an operating system's kernel layer. It can be thought of as partitioning a single physical server into multiple small computational partitions. Hyper-V will include the ability to act as a Xen virtualization hypervisor host allowing Xen-enabled guest operating systems to run virtualized. Hyper-V is not currently part of Windows Server 2008, but will ship within 180 days after Windows Server 2008 is released, as both a standalone product and as part of special "with Hyper-V" editions of Windows Server 2008. Both will only support the x86-64 architecture.


Windows System Resource Manager
Main article: Windows System Resource Manager
Windows System Resource Manager (WSRM) is being integrated into Windows Server 2008. It provides resource management and can be used to control how much resources a process or a user can use based on business priorities. Process Matching Criteria, which is defined by the name, type or owner of the process, enforces restrictions on the resource usage by a process that matches the criteria. CPU time, bandwidth that it can use, number of processors it can be run on, and memory allocated to a process can be restricted. Restrictions can be set to be imposed only on certain dates as well.


Server Manager
Server Manager is a new roles-based management tool for Windows Server 2008[10]. It is a combination of Manage Your Server and Security Configuration Wizard from Windows Server 2003. Server Manager is an improvement of the Configure my server dialog that launches by default on Windows Server 2003 machines. However, rather than serve only as a starting point to configuring new roles, Server Manager gathers together all of the operations users would want to conduct on the server, such as, getting a remote deployment method set up, adding more server roles etc and provides a consolidated, portal-like view about the status of each role.

It is not currently possible to use the Server Manager remotely, but a client version is planned.


Other features
Other new or enhanced features include:


Core OS improvements
Fully multi-componentized operating system.
Improved hot patching, a feature that allows non-kernel patches to occur without the need for a reboot.
Support for being booted from Extensible Firmware Interface (EFI)-compliant firmware on x86-64 systems.
Dynamic Hardware Partitioning
Support for the hot-addition of processors and memory, on capable hardware.
Support for the hot-replacement of processors and memory, on capable hardware.

Active Directory improvements
A new "Read-Only Domain Controller" operation mode in Active Directory, intended for use in branch office scenarios where a domain controller may reside in a low physical security environment. The RODC holds a non-writeable copy of Active Directory, and redirects all write attempts to a Full Domain Controller. It replicates all accounts except sensitive ones. In RODC mode, credentials are not cached by default. Moreover, only the Domain Controller running the PDC-Emulator needs to run Windows Server 2008. Also, local administrators can log on to the machine to perform maintenance tasks without requiring administrative rights on the domain.
Restartable Active Directory allows ADDS to be stopped and restarted from the Management Console or the command-line without rebooting the domain controller. This reduces downtime for offline operations and reduces overall DC servicing requirements with Server Core. ADDS is implemented as a Domain Controller Service in Windows Server 2008.

Policy related improvements
All of the Group Policy improvements from Windows Vista. Group Policy Management Console (GPMC) is built-in. The Group Policy objects are indexed for search and can be commented on.[11]
Policy-based networking with Network Access Protection, improved branch management and enhanced end user collaboration. Policies can be created to ensure greater Quality of Service for certain applications or services that require prioritization of network bandwidth between client and server.
Granular password settings within a single domain - ability to implement different password policies for administrative accounts on a "group" and "user" basis, instead of a single set of password settings to the whole domain.

Disk management and file storage improvements
The ability to resize hard disk partitions without stopping the server, even the system partition. This applies only to simple and spanned volumes, not to striped volumes.
Shadow Copy based block-level backup which supports optical media, network shares and Windows Recovery Environment.
DFS enhancements - SYSVOL on DFS-R, Read-only Folder Replication Member. There is also support for domain-based DFS namespaces that exceed the previous size recommendation of 5,000 folders with targets in a namespace. [12]
Several improvements to failover clusters (High-availability clusters).[13]
Internet Storage Naming Server (iSNS) enables central registration, deregistration and queries for iSCSI hard drives.

Protocol and cryptography improvements
Support for 128- and 256-bit AES encryption for the Kerberos authentication protocol.
New cryptography (CNG) API which supports elliptic curve cryptography and improved certificate management.
Secure Socket Tunneling Protocol, a new Microsoft proprietary VPN protocol.
AuthIP, a Microsoft proprietary extension of the IKE cryptographic protocol used in IPsec VPN networks.
Server Message Block 2.0 protocol in the new TCP/IP stack provides a number of communication enhancements, including greater performance when connecting to file shares over high-latency links and better security through the use of mutual authentication and message signing.

Improvements due to client-side (Windows Vista) enhancements
Searching Windows Server 2008 servers from Windows Vista clients delegates the query to the server, which uses the Windows Search technology to search and transfer the results back to the client.
In a networked environment with a print server running Windows Vista, clients can render print jobs locally before sending them to print servers to reduce the load on the server and increase its availability.
Event forwarding aggregates and forwards logs of subscribed Windows Vista client computers back to a central console. Event forwarding can be enabled on the client subscribers from the central server directly from the event management console.
Offline Files are cached locally so that they are available even if the server is not, with copies seamlessly updating when the client and server are reconnected.

Miscellaneous improvements
Windows Deployment Services replacing Automated Deployment Services and Remote Installation Services. Windows Deployment Services (WDS) support an enhanced multicast feature when deploying operating system images.
Internet Information Services 7 - Increased security, xcopy-deployment, improved diagnostic tools, delegated administration.
An optional "Desktop Experience" component provides the same Windows Aero user interface as Windows Vista, both for local users, as well as remote users connecting through Remote Desktop.

Backup to tape using Windows Backup

Editions
Most editions of Windows Server 2008 are available in x86-64 (64-bit) and x86 (32-bit) versions. Windows Server 2008 for Itanium-based Systems supports IA-64 processors. The IA-64 version is optimized for high workload scenarios like database servers and Line of Business (LOB) applications. As such it is not optimized for use as a file server or media server. Microsoft has announced that Windows Server 2008 is the last 32-bit Windows server operating system.[16] Windows Server 2008 is available in the editions listed below,[17] similar to Windows Server 2003.

Windows Server 2008 Standard Edition (x86 and x64)
Windows Server 2008 Enterprise Edition (x86 and x64)
