Have you checked your DNS settings? Can you ping the NetBIOS name of the DC
and get the full name (server.domain.whatever) in reply?
All servers and workstations should specify *only* the internal
AD-integrated DNS server's IP address in their network settings. The
AD-integrated DNS server should be set up with forwarders to your ISP's DNS
servers for external resolution. See
http://support.microsoft.com/default...b;en-us;300202 for more
info.
