Muito obrigado, Elcio! Você é o melhor! Wow. What a discovery! According to Q312864 IE6 AutoDiscovery using DHCPP option 252 cannot work in Win 2k or Win XP for regular domain users!!! The users have to be members of the Admin or Power Users (or some new "Network Configuration Operators" group in XP) to have permission to query the DHCP server! Amazing. Anyone know how to give users just this permission to issue DHCP queries, rather than making them members of a group with much broader permissions? In any case, I made my users members of that Network Configuration Operators group in Windows XP and it still doesn't work. :( Thus I'm quitting my attempt to use ISA's AutoDiscovery -- I'll either hard code the ISA's IP address in the client's browsers or like Elcio suggested assign some configuration script thru a GPO (anyone knows of a script that figures out what AD site you're in -- or no site at all for say a laptop outside LAN?)

Try to see this article (Q312864 - Automatic Proxy Discovery in Internet Explorer with DHCP Requires Specific Permissions) I had the same problem with a test setup similar as yours. If you use W2K AD, apply the Configuration Script through GPO to your web Clients or apply the IP and port of your ISA Server. You can also clear the Automatically Detect Settings from IE Clients and use the Firewall Client to handle the requests. This option may lose log information colected from web proxy log because you'll begin to see only Firewall Sessions. If the Web Clients (IE's) have both flags (Automatic Configuration) they'll experience a little delay but IE will use the Configuration Script as soon it can't find the firewall. Good luck!
