Hi,

I have a urgent need to demote a 2003 DC server. The server was offline for over 60 days and it appears to have tombstoned. The server was offline and due to a network issue and now users are having issues logging in to their workstations, etc

The server has no roles attached to it and is not a GK server. I'm getting replication issues on my good DC.

The error I receive is - The operation failed because:


Managing the network session with  ****.local failed.

'Logon failure. The target account name is incorrect.


How do I demote this server?

On my good DC it says in event viewer under directory service -


Event ID  - 2042  -  

Source NTDS replication.

Description - It has neen too long since this machine last replicated with the named source machine. The time between replicatins with this source has excedded the tombstone lifetime. The source machine may still have copies of object that have been deleted.

On the 'bad' DC -


Error event ID  1864  -


The local domain controller has not recently received replication information from a number of domain controllers. The count of domain controllers is shown, divided in to the following intervals.

Ok I've deleted the DC using the metadata cleanup and it's been removed from DNS. Only 2 DCs are now in AD. I did not DCPROMO /force, i deleted the server through meta data cleanup

Unfortunately I logged on to a few PCs and some allowed access but others did not as before.  I don't understand why sometimes I can logon to a PC but others i can't . The message when trying to logon states 'a domain controller could not be found, etc...'


There was still an issue that when a users password was changed in AD and they were forced to change it, it never asked for them to change it.

Any further guidance?
