No, it doesn't look at resolv.conf. It either uses a compiled-in set of 
"hints" for the root servers, a "hints" file that you explicitly 
provide, or forwards to nameservers that you explicitly configure.

So, bottom line, if you haven't configured anything special, it's using 
the compiled-in root hints, and you need to make sure that you have DNS 
open through your firewall from the internal nameserver to every 
possible nameserver that you might want to query for DNS.
