    Proxy Settings Failing to Apply

    Hi all,

    Having problems with some machines in which certain accounts cannot browse the Internet.

    As far as I can work out, this is related to Proxy Settings not applying.

    This is also related mainly to some 'Exam Accounts' that we use - but it has popped up elsewhere at random in the domain. This is normally fixed with a quick restart - the 'Exam Accounts' still don't connect after a reboot.

    The only additional group policy settings that apply to these accounts are default profiles and drive maps. Everything else is identical to a generic 'ManagedUsers' GPO, in which the proxy setting is applied through the Polices/Windows Settings/Internet Explorer Maintenance/Proxy Settings.

    RSOP shows the policy has succeeded.

    GP logs on the client show that the GPO has applied.

    winsock resets will temporarily solve the problem.

    I'm seeing some wpad traffic broadcasts on wireshark but autoconfig proxy settings are set to disabled.

    Getting pretty stuck. Any help appreciated! I'm sure I've forgotten plenty of detail, let me know.

    No duplicate proxy settings found.

    However, if the machine is restarted sometimes the internet will connect - this seems to be random after each consecutive restart.

    Which browser are you using? I've had proxy settings disppear when WSUS ran an upgrade to Internet Explorer 10. I ended up uninstalling the IE10 upgrade and running IE10 blocker as it was a complete nightmare!

    IE9 and Chrome. Doesn't seem browser related, but you never know!

    I've just created another account, blocking all inherited GPO's to that OU and applied a simple GPO for proxy settings.

    Internet works 100% on that, so it must be a GPO causing the problem?

    We are using that version yep, but not wpad.

    It's only effecting the newest users, but the majority of our default profile users for some reason.

    Getting there, slowly...

    This seems very strange.

    A couple of users with the problem report that their internet came back when they tried to refresh the page. No restarts or log offs.

    Network issue?
