Have a new installation of Windows 2008 R2, with AD & DNS installed and configured. I could not get a second machine to join the domain after trying everything I could find on the support forums, I disconnected the router from the switch - thereby
disconnecting the network from the Internet. That solved the problem I joined the second machine to the Domain, nslookup found the machine and the DNS records were updated. As soon as I plug the router back in it seems that the DNS or AD stops working. Any
ideas would be welcome. The router is providing the DHCP and is the gateway.
