I have an old server that has been offline for more than 6 months. Now I need to cleanup my network to get this server removed as a DC and Exchange server. The server is Windows Server 2003, the current DCs are 2008 R2.
I have confirmed that the network is set to a Server 2003 functional level.
When I try to 'dcpromo' the server, or 'Replicate Now' in AD Sites and Services, I received one of the two following errors:
The RPC Server is unavailable.
Insufficient attributes were given to create an object. This object may no exist because it may have been deleted and already garbage collected.
I have already tried 'repadmin /removelingeringobjects...'
I have disabled the setting for Strict Replication on the old server
How can I get the old server replicated or at least able to demote adn remove exchange cleanly?
