Right now I have two servers running AD and DNS. Both are running server 2003. I have a newer server running Server 2008R2 that I would like to add as a DNS server so I can then remove that role from one of the 2003 servers.
I have installed the DNS role on the 2008R2 server, and from DNS on the 2003 server I have added the 2008R2 server to the snap in, but I get a red x over it and a message that it can’t connect to the DNS server. The server is up, has a valid IP. Is there somethign I need to do inorder for the 2003 server to recognize DNS on the 2008R2 machine?
