DNS 101:
All AD machines (DCs, member servers and clients) MUST always and ONLY use
the internal DNS server(s) that AD is using in their IP properties. If using
DHCP for your clients, make sure Option 006 ONLY lists the internal DNS
server(s) that AD is using.
For Internet resolution, DNS will use the root hints. If you want efficient
resolution, you can use a Forwarder to your ISP's DNS server. That is set in
DNS properties, Forwarders Tab.
If that rule has been followed, and you are still experiencing problems,
please post: an ipconfig /all from your DC and one of your clients.
Thanks!
