Hello. I am sitting inside an ISA Server trying to access OWA at HQ. If I bypass the ISA Server, and go straight out through the external firewall on dynamic nat, I connect to the site, enter my password details and OWA loads. If I proxy through the ISA Server, which has one nic on the internal subnet, and one nic in the DMZ of the perimeter firewall, OWA keeps prompting for my password time and time again. Is this a latency issue, or is there something that needs to be configured in ISA for auth traffic to pass freely?
