Hi Group, Well, I believe I have discovered the issue. Leave it to Microsoft to screw things up. (I love how they specifically noted Squid in the KB article I will link to below.)
Apparently they got this great idea (and it actually isn't a bad idea) to go ahead and implement something called the Automatic Proxy Result Cache. In a nutshell, it had cached an old version of the proxy configuration information, and therefore wasn't updating it. See this link for more on it: http://support.microsoft.com/default.aspx?scid=kb;en-us;271361 Well, rather than play around with the registry, I believe I may have found a somewhat simpler solution. Basically all you have to do is in Internet Options, uncheck the Automatically Detect Settings box, close IE (if that's how you got to the Internet Options box), then re-open it. Go back in, check the Automatically Detect Settings box, close it, then re-open it. It should have then downloaded the new wpad.dat file. I used Ethereal to confirm that it did indeed work. Now, since I was testing this on an XP box, I logged out and tried it with my user name. Same problem as I originally had. Did the above, and it worked beautifully. According to the KB article, Microsoft implemented this in IE 5.5. That explains too why I had no problems with the Windows 98 box I was playing with as well, since it had reverted back to IE 5. It was definitealy a strange (yet interesting) problem. Took me a while to figure it out, and a lot of head banging on the keyboard, wall, door, etc. Hope that helps anyone else who may run into this problem! Cheers!
