We recently changed the domain name of a AD network from xxx.com to hq.xxx.com. I did not do the change, and there were a number orphan records left laying about in the DNS. Theses were mainly pointing to the DC server.xxx.com. They should have of course been pointing to server.hq.xxx.com.
I was able to clean almost everything up.
I have left 3 "Reverse Lookup Zones" that all refer to server.xxx.com, instead of server.hq.xxx.com. I do not see anyway of editing or changing these zones. I have restarted DNS, I have restarted ADS which restarts DNS. and the reverse lookup zones stay the same.
This is a single DC domain. There is only one DNS server on the domain.
As I have been typing this I noticed another anomalysome of the _ldap and _kerberos entries buried in the forward lookup zone _msdcs->dc->_sites->Default-First-Site-Name pointing to the old domain have grown back.
I suspect this last issue is related to the first, can anyone help with this?
I did a bit more digging, and found in Active Directory Users and computers under the new domain the Domain Controller the Domain Controller server computer has the old dns name, ie server.xxx.com. I do not see an easy way to change this, and it seemed imprudent to delete it and try and recreate it.
Still need help.
