Important

In a Web Proxy chaining scenario, user names and passwords can be specified using 7-bit characters only. Otherwise, Integrated Windows authentication will fail on the downstream proxy server.
We recommend that you specify the upstream computer's IP address, rather than its name. Also, on the upstream computer, configure the Firewall Client settings to manually select an ISA Server computer. Then, specify an IP address for the ISA Server computer, rather than a fully qualified domain name (FQDN).
