| Description |
|---|
| Non-vendor supported versions of AD are not permitted for use in DoD. Domain controllers using Windows NT and Windows 2000 are no longer supported or updated by the vendor. If Windows NT or Windows 2000 domain controllers are used in AD domains, the level of security in the domain and forest is significantly reduced because many advanced features of the directory are not available. Further Policy Details: Raising the domain functional level to Windows Server 2003 or higher is a non-reversible task. This action prevents the addition of Windows NT- or Windows 2000–based domain controllers to the domain. Any existing Windows NT- or Windows 2000–based domain controllers in the environment will no longer function. |
