The internal does not resolve outside adresses, it fowards them to the DMZ.......if an Nslookup is done on an internal DNS server for an outside address such as www.msn.com it returns a non authoritative answer at it should ....But the internal server was unable to give out unauthoritive answers, i restarted the service which solved the problem.....i am curious as to why this might happen?

This is a case where the internal DNS would not forward its request to the DMZ  ? Because an non authoritative answer was not given.  I restarted the DNS service and it was then able to unauthoritative answer.  i wil chweck the event log..just checking for any other issues that might cause this thanks,...
