What are the Major differences between windows server2003 and windows server2008
The main difference between2003 and2008 is Virtualization, management. 2008 has more inbuilt components and updated third party drivers Microsoft introduces new feature with2k8 that is Hyper-V Windows Server2008 introduces Hyper-V (V for Virtualization) but only on64bit versions. More and more companies are seeing this as a way of reducing hardware costs by running several 'virtual' servers on one physical machine. If you like this exciting technology, make sure that you buy an edition of Windows Server2008 that includes Hyper-V, then launch the Server Manger, add Roles.
In Windows Server2008, Microsoft is introducing new features and technologies, some of which were not available in Windows Server2003 with Service Pack1 (SP1), that will help to reduce the power consumption of server and client operating systems, minimize environmental byproducts, and increase server efficiency. Microsoft Windows Server2008 has been designed with energy efficiency in mind, to provide customers with ready and convenient access to a number of new power-saving features. It includes updated support for Advanced Configuration and Power Interface (ACPI) processor power management (PPM) features, including support for processor performance states (P-states) and processor idle sleep states on multiprocessor systems. These features simplify power management in Windows Server2008 (WS08) and can be managed easily across servers and clients using Group Policies.
