Problem

I saw this error while attempting to install an update on Exchange 2010, but it can be seen on all flavours of Exchange. This is the ‘gist’ of the error;

Solution

This was an easy one to sort out, on one of your domain controllers open “Active Directory Sites and Services”, expand all the sites and look at the server names. In my case there was an old DC in the list (these are usually easy to spot as you cant ‘expand’ them), i.e.theres no NTDS settings below them.

Simply right click the offending server and delete it, then either force domain replication, or wait a while.
