I am preping for a migration to 2003 AD. I configure the first DC runing DNS. I am successful in creating a trust to my production NT domain and can join users to the new domain. Interent name resoultion just stops working after initial install. My root servers are listed, simple and recursive queries test OK. If I add my local ISP as a forwarder it also starts to work then fails after several hours. I am running a 2000 DNS server on my NT domain with no problems. The only difference is my NT domain is not a registered FQDN and my new 2003 doamin is. When I run an NSlookup everything points to itself (the local box) even if I perform a NSlookup on yahoo.com. I'm getting tired of rebuilding the O/S.
