Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
The Microsoft® Windows® Server 2003 Active Directory® directory service enables you to introduce advanced features into your environment by raising the domain or forest functional level. You can raise the functional level when all domain controllers in the domain or forest are running an appropriate version of Windows. Raising the functional level allows you to introduce new features but also limits the versions of Windows that can run on domain controllers in your environment.
