The good news is that its not an ISA firewall or SP2 problem. The bad news is that its something else.

OWA has not been working after the installation of ISA Server 2004 SP2. Users can connect to OWA within the internal LAN but not when trying to connect from the outside world. I have checked out the logs but I don't see anything indicating problem with OWA. When users try to connect from the outside world, they get the error "cannot find server or DNS Error". Anyone out there experienced this problem before? Please, share with me if you have and how you were able to resolve this problem. Thanks. Tony
