Definition The characteristics of groups in Active Directory depend on the domain functional level. Domain functionality enables features that will affect the entire domain and that domain only. Three domain functional levels are available: Microsoft Windows® 2000 mixed, Windows 2000 native, and Microsoft Windows Server 2003. By default, domains operate at the Windows 2000 mixed functional level. You can raise the domain functional level to either Windows 2000 native or Windows Server 2003.
The table above lists the domain functional levels and the domain controllers and group scopes they each support.
Note You can convert a group from a security group to a distribution group, and vice versa, at any time, but only if the domain functional level is set to Windows 2000 native or higher.
