have you seen this error before:
This error can be caused of the DC of holding the RID FSMO is failed to contact and have been deleted.
Check the FSMO holder by running NETDOM QUERY FSMO.
this could mean that the metadata cleanup of the deleted DC is performed.
1. try to transfer FSMO to the other existing domain controller.
We need to seize the FSMO role.
2. as Step 1 has failed, use seizing the FSMO role by NTDSUTIL.
-> Connect to Server <DomainController>
-> Seize rid master
verify the FSMO has been moved to other Domain controller.
