I want to demote last DC in a site and it will do the final replication but then when netlogon is shutting down, it times out and fails to demote due to timeout. When checked in the event log, the DNS server encounters a critical error from Active Directory and the event is 4015 with the below error:
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "000020DE: SvcErr: DSID-030F00E 4, problem 5001 (BUSY), data 0". The event data contains the error.
Dcpromo ends by saying that Active Directory was not removed and I will then restart since AD will work fine after that. Any help would be appreciated.
