Currently I have two AD Domains with their own DNS and we want to eliminate one of them as the second domain is no longer needed.
Domain 1 and Domain 2 have a full trust setup between them. I have already disjoined and re-joined all the machines from Domain 2 into Domain 1. Most of the machines in Domain 2 are statically assigned IPs - their DNS info has been updated to point to Domain 1 AD/DNS servers. The rest are setup through DHCP and DHCP as been updated with Domain 1 info for DNS settings.
The problem I am running into is for the IP range the former Domain 2 machines have been assigned the reverse lookup zone still is tied to Domain 2 and I am wondering how I can move it into Domain 1?
Domain 1 is a Windows 2008R2 Domain and Domain 2 is a Windows 2003R2 Domain.
Some background info:
Domain 2 was a turnkey solution from a vendor - so the domain/application was dropped into the environment way before my time. Recently we did a hardware refresh with the vendor and during that process the new servers were joined to domain 1. The only thing was we needed to use the same IP addresses. So the DC/App server IP addresses of Domain 2 were reused for the new App servers that were joined to Domain 1. So Domain 2 DCs were re-ip'd and currently sitting idle as we have confirmed the app/hw refresh went well now I just need to finish the cleanup.
