Hi I am experiencing a peculiar problem with OWA. When a user tries to access the Exchange server using the FQDN of the Exchange site he gets the following error: "403 Forbidden - The server denies the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) Internet Security and Acceleration Server" Accessing the Exchange site using the IP address of the external Interface of the ISA Server works fine. The FQDN name of the site does resolve to the same IP address. Could anybody shed light here?
