Windows 2008 upgrade

Can someone tell me about the good reason of upgrading from windows 2003 to windows 2008.
Who is Participating?

There are a lot of improvements and new features introduced in Windows Server 2008 which can - in many cases - warrant an upgrade of your servers to Windows Server 2008. Hyper-V, new Active Directory features, the improvements in Terminal Services (TS Gateway, TS RemoteApp and so on) are just some of the features.

See for details on some of the new features.

Hyper-V is you have vmware you don't need Hyper-V
If you have Citrix yo don't need TSRemoteAapp
Server Core sounds to me just like Windows 2003 adding/removing roles
High Availability, windows 2003 also has it.

The rest I don't see big importance.

Server Core is a lot more than simply a different way of adding / removing roles. It is a whole new way of working. It takes away the GUI interface, meaning you make use of the Command Line or remote tools to interface with the server. It makes your server a LOT more secure since the attack surface and number of bugs is significantly reduced.

VMWare and Hyper-V are undoubtedly competitors. In this case, it is what you prefer. Personally, I have no problem with either product and would happily implement either one in a virtualisation situation.

TS Gateway is a brilliant addition which I have yet to see a good match for. It vastly improves - and simplifies - your possibilities for remotely accessing many Terminal Servers quite easily.

There are also hundreds of Active Directory improvements, such as the improvements to AD Domain Services which allow fine-grained password policy control as just one example. This is not possible in Server 2003. You also have the introduction of AD Light Weight Directory Services, AD Federation Services and several other Active Directory roles.

Server 2008 is the platform which integrates well with Windows Vista. It has out-of-the-box support for the configuration of the new Vista Group Policies, Group Policy Preferences and so on.

It is also one of the most secure Microsoft Operating Systems released to date.

There are a lot of improvements in Server 2008 which make it far superior to Server 2003. I have been running it in several places for nearly a year and have been very impressed with its increased performance and productivity, as well as security.
