I have a ISA Configuration looking like this: Internet - ISA1 - DMZ - ISA2 - Intranet The DMZ and Intranet are using 192.168.x.xxx addresses. On the intranet is a Exchange Server 2000 with the "integrated" IIS web mail functionality. I want to read the web mail from internet and therfore trying to publish the exchange webserver via ISA2 and publish the ISA2 via ISA1. Since exchange web mail relies on hostname I need to push the hostname all the way through both ISA servers. However, doing this I get the following error message when i browse this page from the internet: 403 Forbidden - The server denies the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) Internet Security and Acceleration Server Any tips or ideas? BR/Jonas
