RE: [squid-users] WPAD and Internet Explorer 6

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...

When you say you found nothing with Ethereal, did you see any name
resolution activity? - were you able to verify a successful resolution
of the wpad host name against the correct domain, and that an attempt
was made to retrieve the wpad.dat file using http? How far did it get?

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...

TIA
