    the-practical-proxy-pac-file-guide.pdf^^ exactly that.
    If you can push it by DNS/DHCP then it may yield some progress, or at the very least an answer.

    As i said before GPO working fine, IE is picking it up and setting it. If i get a standalone machine and set it manually i get the issue. I only got problems when the LEA started tinkering.

    }
    That might help diagnose whether the problem had anything to do with your particular pac code.
    Just tried this and no chage. Thanks anyway.

    Then I imagine all that is left is routing?
    can the system ping/route to the IP to which the pac file is associated?

    Sat here scratching my newly cultivated beardyness.... thinking this is probably already on your list.

    You say they added in load balancing - they haven't as part of that restructured the IP range (ie there's a new load balanced IP)? Simple thing I know... but netsweeper and LEAs do the strangest things!

    actually routing is the sensible thing to check. well picked up @DT2. I would check that to be sure.

    Sorry I never noticed this thread got updated.

    At this point I would try using a packet sniffer like Wireshark or Microsoft Network Monitor. I would try to catch one of the HTTP GET messages going out for which no web page was returned. I would then compare that to a successful GET message, for example sent out with the proxy entered manually (which you said always worked).
