REPOST: unable to locate server after upgrade to BIND 8.2.3 for NT

         I think you need to just set the forward to "forward only".  If you are behind
a firewall, then your server cannot access the Internet directly to answer the
query itself, which is what "forward first" would do if the forwarder does satisfy
the query and it's not in cache.
