I can see name resolution activities from Windows 2000 and XP PCs but not from NT4 workstations. Like I mentioned in my previous post, if I specify the automatic configuration script (the URL to the wpad.dat file) I can see the NT4 workstation issue the "GET /WPAD.DAT" command from Ethereal. Again, if I set it back to "automatically detect settings" (even did a reboot after the change), does not work, nothing DNS related in Ethereal...

How far did it get? -----Original Message----- From: Damien Nguyen [mailto:dnguyen@xxxxxxxxxxxxxx] Sent: 15 April 2005 18:36 To: squid-users@xxxxxxxxxxxxxxx Subject: [squid-users] WPAD and Internet Explorer 6 Hi, Some background: Squid 2.5Stable9 (running with FC3) Apache server (running on on the same PC as SQUID) Mixed of NT4, 2000 and XP client operating systems. I followed the Squid-cache.org FAQ as much as I could and got Squid to work. I am using WPAD via the DNS method. The issue I am having is that for some reason I cannot use the "Automatic detect settings" in Internet Explorer (latest version 6) and it seems to only happen on NT4 PCs (both workstations and servers). Windows 2000 and XP clients works fine. If I changed the IE setting on the NT4 PCs to "Use automatic configuration script" and specify the address (to the WPAD.DAT file on the Apache server) it work fine. Manual setting worked as well. Only when I specify "automatic detect settings" then it stopped working. I use Ethereal to check for any communication between the SQUID PROXY PC and NT4 client when IE6 start up and found nothing. I made links to the wpad.dat file using wpad.da, proxy.dat, proxy.pac and that did not help. Any idea why WPAD only works with 2000 and XP clients and not NT4. All clients use Internet Explorer 6. I even tried Mozilla FireFox 1.0.2 on the NT4 clients and that made no difference...
