Hi all. I am at wits end trying to get WPAD working correctly on my network. I have an ISA 2004 server (SP2) which is acting strictly as a web proxy/cache server. It is a unihomed machine. This machine is also acting as our content filter device. It is running a program called Smart Filter for this purpose.
I have set up WPAD via DHCP and DNS following microsoft technet articles to the letter. On my ISA server I have configured Auto Discovery for port 80. I have tried other ports as well. My web proxy is set up on port 8080. In Internet Explorer, if I manually pick my proxy server it works perfectly. But as soon as I choose to Automatically Detect Settings, proxy no longer works. I instead make a direct connection to the web. I have verified that wpad.dat and wspad.dat exist on the ISA server by going to I am presented with a download option when I go to that location so I know it's working correctly. I even tried moving these files to another server running IIS for testing purposes. Once again it did not work. I cannot figure out where this is failing. Any ideas?
