I am trying to add a new DC to an existing forest. The existing forest, is a server 2008 machine on subnet 172.30.x.x and the new DC I am trying to add to it, is a server 2003 machine on subnet 172.29.x.x. When i first created the Domain, I made sure to set it to a serve 2003 Domain.
When I try to add the server 2003 DC to the domain, it says “An active directory domain controller from domain “mydomain.local” could not be contacted. Enter a DNS Domain name that is typed correctly.”
My guess is that it is a DNS problem, but I’m not sure how to fix it. Both machines have DNS installed, and I set the secondary DNS of the Server 2003 machine to the IP of the 2008 machine. I created an A record in the reverse lookup of the DNS on the Server 2003 machine, but that didn’t seem to help. If I try to ping the machine name of the 2008 server from the 2003 server, it does not resolve.
Any help would be appreciated.
Thanks
