When trying to add a new Windows 7 machine to a network I get the following error message..."An attempt to resolve the DNS name of a DC in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resolve DNS names in the target domain." I don't have any problems adding XP machines to the domain and not sure why I can't add a Windows 7 machine. I am able to get on the internet on the Windows 7 PC but can't add it to the domain.pliz assist.
