Win 7 WPAD stops working

Discussion in 'Windows Vista Networking' started by Jeff Vandervoort, Mar 19, 2010.

  1. I use my Win 7 notebook on an office network with a proxy during the day,
    and on my home network w/o proxy at night. Used to be that WPAD configured
    the proxy settings for me, but it stopped working a week or two ago; don't
    recall when. I have to manually turn on "Use a proxy server" at the office
    and turn it off again at home. "Automatically detect settings" is turned on.

    Any idea how I can get it working again?

  2. I guess I should also mention that WPAD is working elsewhere in the office
    network, despite not working not on my machine. And I can download
    http://wpad.domainname.local/wpad.dat on my machine.

  3. More info, in the increasingly unlikely case that anyone can actually help
    with this...

    I renamed the
    Settings\Wpad key, and let Windows create a new one. And it did, and with
    the same values as were previously set for these networks.

    Home network (no proxy):
    WpadDecision = 0
    WpadDecisionReason = 1

    Work network (proxy):
    WpadDecision = 1
    WpadDecisionReason = 0

    Since I don't find documentation for these registry values, I don't know if
    the right decision is being reached, but given that they're opposite,
    there's a good chance. It's clearly detecting a difference.

    So then the question becomes, why isn't Windows changing proxy settings
    between the two systems?
