Hi. I don't have an internal domain.  Can you direct me to some help documents.

        I have had this problem too.  I ended up moving my DNS Server outside 
of the firewall. 
        
        Are you not getting any error messages in the even logs?  Just no DNS 
at all from the outside?  Does rebooting the server fix the problem 
temporarily?  Restarting the services wont though.  If so, then it appears we 
are having the same problem.  I'm still waiting for a fix.

        No, the DNS server is not running on a DC.
        I REALLY dont think it is a DNS issue.. Im pretty sure this is an ISA 
issue.
        the reason I say this is because I could NSLOOKUP from my internal 
network to that DNS server and get perfecly good resposes. but, if I tried to 
NSLOOKUP from outside, I got no response at all.
