RE: [squid-users] IE5/Win2k/WPAD not working

Hi Diego,

The problem sounds like the issue that I have. Check this link (look
for the info about automatic proxy result caching):

http://support.microsoft.com/default.aspx?scid=kb;en-us;271361

Sounds to me it's a problem where IE is caching the result. If you
already had it enabled prior to implementing the proxy, I haven't found
any easy way around it. If you hadn't had it enabled, everything should
work fine.

I used my personal laptop for a while between work and home, on two
separate networks using DHCP to set my IP addresses and such. What I
found was that once I was able to successfully connect to the Internet
from home with those settings, and then bring it back to work, it
detected the proxy just fine. But, prior to that when I was just
testing it strictly on the work network (and also with other computers),
it simply wouldn't cooperate.

Leave it to Microsoft to try to make things more efficient, but give
others migraines in the process.

Hope that helps, what little it may.

Regards,
Scott

I'm not using DHCP, so rather than fallback they should become the
primary mechanisms, right?

Anyway, I'll be sure to add the parameter to DHCP just in case (even
though it's not being used!).

That's exactly my point: DHCP is not being used and not providing the
info, so it should go to failback mechanisms. But it's not even trying
to use the failback mechanisms: packet sniffs confirm that no attempt is
made to resolve wpad.mydomain.com, http logs confirm that no attempt is
made to retrieve http://wpad/wpad.dat, which is what is documented!

Anyway, thanks for your help, and does anyone have any other
suggestions? The reason this needs to work is because some road
warriors use laptops which need proxy while on-site, but don't use it
(proxy) while off-site (thus, the auto-detect setting is crucial to keep
them from having to change configurations).

Best
