This is the error page I get when trying to view a intranet server based at our other site:
Going through the usual gateway this is no issue
The requested URL could not be retrieved
The following error was encountered while trying to retrieve the URL:
Unable to determine IP address from host name intranet-site-nameThe DNS server returned:
Server Failure: The name server was unable to process this query.This means that the cache was not able to resolve the hostname presented in the URL. Check if the address is correct.
