dhcp + wpad + firefox

I've got a load balanced wpad service set up here using 3 servers front
ended by a Foundry ServerIron which does load balancing across the 3
real servers. All works just fine for IE but not for firefox. The beta
safari browser I'm using also seems to work.
I've got wpad.hull.ac.uk set up as a virtual host on each of the 3

In my dhcpd.conf file I've got

option wpad-url code 252 = text;
option wpad-url "http://wpad.hull.ac.uk/wpad.dat";

I've got a number of log files set up on the real servers :-
One for each virtual host 
One for a "default" server if someone tries to access the server via its
ip address.

It looks as if IE access wpad.hull.ac.uk/wpad.dat ( unless you've got an
old version of ie6 that asks for wpad.hull.ac.uk/wpad.da )

However as far as i can see, firefox seems to resolve the domain into
its ip address and then ask for http://a.b.c.d/wpad.dat, at least i
think it does that coz there are an awful lot of http requests going
into the default server.

Anyway I can't seem to get firefox to work with autodetect proxy

We have this setup working with both FF and IE with option 252 too.
The DHCP is one component of this setup. Other is ur web server, ie.
Give us more details.

The two basic principles of Windows system administration:

   * For minor problems, reboot
   * For major problems, reinstall

dc -e
