Product Description :
Microsoft Windows Server 2008 is the next generation of the Windows Server operating system that helps information technology (IT) professionals maximize control over their infrastructure while providing unprecedented availability and management capabilities, leading to a significantly more secure, reliable, and robust server environment than ever before. Windows Server 2008 delivers new value to organizations by ensuring all users regardless of location are able to get the full complement of services from the network. Windows Server 2008 also provides deep insight into the operating system and diagnostic capabilities to allow administrators to spend more time adding business value.
Windows Server 2008 is far more than a refinement of predecessor operating systems. Windows Server 2008 is designed to provide organizations with the most productive platform for powering applications, networks, and Web services from the workgroup to the datacenter with exciting, valuable new functionality and powerful improvements to the base operating system.
Windows Server 2008 Enterprise delivers an enterprise-class platform for deploying business-critical applications. It helps improve availability with clustering and hot-add processor capabilities; improve security with consolidated identity management features; and reduce infrastructure costs by consolidating applications with virtualization licensing rights. Windows Server 2008 Enterprise provides the foundation for a highly dynamic, scalable IT infrastructure.
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.
Dynamic Hardware Partitioning
Support for the hot-addition or replacement of processors and memory, on capable hardware.
Active Directory improvements
Read-only domain controllers (RODCs) in Active Directory, intended for use in branch office or other 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 replication partner of the RODC 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
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.
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.
Protocol and cryptography improvements
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 ofmutual authentication and message signing.
Windows Deployment Services replacing Automated Deployment Services Windows Server 2008 home entertainment and Remote Installation Services. Windows Deployment Services (WDS) support an enhanced multicast feature when deploying operating system images.
Windows Internal Database, a variant of SQL Server Express 2005, which serves as a common storage back-end for several other components such as Windows System Resource Manager, Windows SharePoint Services and Windows Server Update Services. It is not intended to be used by third-party applications.
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.
