I am having an issue with our SBS Server 200 running Exchange 2000. Our Outlook Web Access works from the internal side, but when trying to access it from a computer outside the network, I receive the error message, "The page cannot be displayed There is a problem with the page you are trying to reach and it cannot be displayed. Eroor 404," from ISA server. I have tried almost everything I can think of, the DNS record is pointing to the proper IP. Any ideas>??
