I have Netflow Analyzer EE 6.5.0 (build 6501) recently installed on a W2K3 server.  When I drill down into a interface to view the specific traffic I am presented with a button 'Resolve DNS'.  When I press this the page refreshes but the IP addresses do not resolve to names.  I can manually resolve the names from a command prompt on the same server.  Any thoughts?

Thanks
