Answer : DNS ISSUES ON ISA2004

Which meand your internal DNS Server is NOT able to go out. Whatever Internet that you are getting, is through the proxy. I think, if we resolve this..we should be able to fix this issue. Is your internal DNS Server pointing to the ISA for the Default Gateway. Do you have any otherfirewall besides ISA in your network? What are you using in your DNS...Forwarders or Roothints to resolve the names..
