Hello, Please restore your DC from a backup that dates before the changes you have done. Perform an authoritative restore for that. How many DCs do you have? How have you changed the DC name? Do you have a DC with a GC other than that one? This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
