0 Sign In to Vote A Windows 7 Professional workstation cannot resolve the name when connecting to a Windows Server 2003. I ran Portqry tool and found an issue with Port 53 and opened this Port in Windows Firewall on the client and Windows Server 2003. However, it still cannot resolve the name and I cannot get the Windows 7 workstation to join the domain. Our DNS server is with the ISP but have enabled DNS on the Windows Server 2003. I can ping the server IP address from the Windows 7 client nslookup does resolve using the FQDN. Any ideas on other settings I need to change/ports I need to open to allow?

You cannot use the DNS service of your ISP if you are running a domain. AD uses the local DNS to find domain resources. Point the workstation to the DC for DNS. You should also modify the local DNS to forward to a public DNS (such as your ISP) so that it can resolve foreigh URLs as well as local names. The client machine should use the local DNS server only. Do not add the ISP DNS address to the workstation, even as a secondary. Bill
