I am running an AD that has been renamed at some point in the past. I don't know when (one of my predecessors did it). I don't know for certain if it has been completed successfully. The only remaining evidence I can find is the msDS-DnsRootAlias attribute still exists causing DNS some issues when trying to update root servers outside of the domain.
I have read the technet article on renaming a domain http://technet.microsoft.com/en-us/library/cc738208(v=ws.10).aspx and I get the impression that the AD would not be in a working state if the rename had not finished.
Does this mean I am safe to run rendom /clean ?
Is there anything I can check other than looking for the log files (Looked I can't find it in old sysadmin user folders or on c:)
