You may have some different setup, but this is what works
for me and seems to work for IE, FF, Opera et al.
For wpad, the browsers should look up wpad locally, 1st --
with no domain, then FQDN like wpad.xxx.example.com, then
wpad.example.com. I also have my internal hosts setup to
lookup hosts on nmb -- so it also serves the hostname.
It shouldn't have to go through the proxy to get the wpad
file -- sorta defeats the purpose.
At a windows prompt, I can do nslookup:
nslookup wpad
Server: ishtar.sc.tlinx.org
Address: 192.168.33.1
Name: Ishtar.sc.tlinx.org
Address: 192.168.33.1
Aliases: wpad.sc.tlinx.org

or from linux:
dig wpad

right, but haven't bothered to track it down, so might wanna ignore it!).

Hope the above helps...it was pretty simple...
