The server is not operational

The Active Directory domain controller cannot be accessed.

Possible Causes

The domain controller may be down or is otherwise unreachable.  One possible cause is that a NetBIOS name is being used to connect to the domain controller instead of its Fully Qualified Domain Name. 

Recommended Fix

Verify that the domain host name is correct and that it can be pinged.
