Changes in Functionality from Windows Server 2003 to Windows Server 2008
In the Windows Server® 2008 operating system, Microsoft is introducing many new features and technologies, which were not available in Windows Server® 2003 with Service Pack 1 (SP1), that will help to increase the security of computers running Windows Server 2008, increase productivity, and reduce administrative overhead. This set of topics describes some of these features and technologies.
These topics apply to the released version of Windows Server 2008. They do not describe all of the changes that are included in Windows Server 2008. Instead, they highlight changes that will potentially have the greatest impact on your use of Windows Server 2008 and provide references to additional information.

New Features in Windows Server 2008
1. 64-bit only—Windows Server 2008 R2 marks the first time that the Windows Server OS will be 64-bit only, meaning that Server 2008 R2 must run on x64-compatible hardware.
2. Support for 256 cores—Improved scalability is another important feature in Server 2008 R2, which will be able to utilize up to 256 cores.
3. Core Parking—Windows Server 2008 R2's new Core Parking functionality enables improved power management. Core Parking lets the OS suspend cores that aren't in use,
4. Remote Desktop Services—Another change in Windows Server 2008 R2 is the rebranding of Terminal Services to Remote Desktop Services. However, the changes aren't in name alone. The new Remote Desktop Services includes support for the Aero Glass interface, multiple monitors, and DirectX 11, 10 and 9.
5. New Hyper-V—A new Hyper-V release is included in Server 2008 R2. A prerelease version of Hyper-V was shipped with the original Windows Server 2008. R2 includes the latest version of Hyper-V. In this version, VMs are able to address up to 32 cores per VM, and the use of TCP Offload and Jumbo Frames provides improved networking performance. One of the biggest improvements in Hyper-V is support for the next item.
6. Live Migration—probably one of the most anticipated features in R2, Live Migration improves VM availability by letting you move Hyper-V VMs between hosts with no downtime.
7. Support for the .NET Framework in Server Core—One of the biggest disappointments in the original Server 2008 release was the lack of support for the .NET Framework in Server Core, which meant that technologies that seemed perfect for Server Core,
8. Power Shell 2.0—Server 2008 R2 includes Power Shell 2.0, which features improved WMI cmdlets and support for running scripts on remote systems,
9. Remote server management—Server Manager was one of the best improvements in Server 2008 because it provides a centralized and useful console for managing Windows Server.
10. Active Directory Administrative Center—For administrators, the biggest change in Server 2008 R2 is undoubtedly the new Active Directory Administrative Center, which replaces the older Active Directory,

New Features in Windows Server 2003
1. Windows Server 2003, Web Edition—Web Edition is one of the most anticipated components of Microsoft's line of server products. Specifically designed for use as a specialized Web server and in Web farms,
2. Integrated support for the .NET Common Language Runtime (CLR)—All Windows Server 2003 editions will come bundled with the CLR, which is a vital stepping stone for future adoption of the .NET Framework. CLR will let .NET applications immediately run on the Windows Server 2003 platform without requiring additional runtime components.
3. The Universal Description, Discovery, and Integration (UDDI) service—All versions of Windows Server 2003 except Web Edition will support the UDDI service..
4. RIS support for Windows server installations—Another welcome addition to Windows Server 2003 is the ability to use RIS to perform Windows server installations.
5. Headless server operations—A long-overdue Windows server feature is support for headless operations. In headless mode, Windows Server 2003 can run without a keyboard, mouse, and monitor.
6. Microsoft IIS 6.0—You'll find some big changes in IIS 6.0, which is bundled with all editions of Windows Server 2003. Now locked down by default, IIS 6.0 sports a more robust architecture,
7. Install Replica from Media—In Win2K AD, performing an initial replication to a branch-office domain controller (DC) over a WAN link can be a painfully slow experience. Windows Server 2003 solves this problem by letting you replicate a complete copy of the AD database to media.
8. Resultant Set of Polices (RSoP)—Addressing another Win2K shortcoming, Windows Server 2003 includes a new RSoP feature that lets you study the net effect of policy settings on users and computers. RSoP can be a powerful aid in debugging policies, particularly because the new planning mode lets you see the effects of new policies before you deploy them.
9. Active Directory Domain Rename—AD's unforgiving nature has always been a big drawback to setting up AD on Win2K. Windows Server 2003 adds some friendliness by letting you change a domain's DNS and NetBIOS names,
10. Microsoft Volume Shadow Copy Service (VSS)—One of the coolest Windows Server 2003 gems is its VSS feature. A volume shadow copy is a point-in-time copy of a given storage location..
