Active Directory Functional Levels Technical Reference
Domain and forest functional levels, introduced in the Microsoft Windows Server 2003 Active Directory directory service, provide a way to enable advanced Active Directory features that are appropriate to the Microsoft Windows Server operating systems running on domain controllers on your network. Different functional levels exist for both domains and forests so that your organization can maximize the capabilities of Active Directory within each domain or forest that you maintain.
Implementation of an Active Directory functional level that supports advanced features of Windows Server 2003 requires more than just the installation of Windows Server 2003 on domain controllers. It requires an understanding of the advanced features that are provided at each domain and forest functional level and how to use Active Directory administration tools to raise the functional level.
