Windows 7 - IE9 - GPO Proxy setting issues

Posted on 2012-09-10
Last Modified: 2012-09-14
Hello, I'm Hoping you may have seen this before.
Windows 7 intermittent internet issue. Stations pull down all GPO settings appart from the proxy server setting. Totally random throughout the domain. Internet Works one minute with one user and not with the next person logging on. We have full lan connection but Internet times out.
Been through the forums, loads of people have the issue but no silver bullet solution. Policies also force refresh on logon but the proxy setting does not take. Windows 7 and IE9 on said stations. XP and IE8 not a problem.

We have two W2k8DC's R2, Sophos on all workstations as well as a standard Office etc build. I have seen several threads on this but noone can seem to pin it down to a Windows 7 bug or setup issue. Any ideas?

    Please see this question from when I had this exact issue.

    It's pretty much just an issue with the IE GPO Processing. Still to this day I have found no "fix" per se. I worked around this in the end by scripting the registry key.

    Thank you, As long as the reg key script works consistently then I'll be a happy man. Have you found any issues doing it this way?

    No issues as far as I can recall - it was a while ago. Just make sure you remove any policies that are trying to apply the proxy first as this will conflict.

    I think you posted your last comment in the wrong question lol. Anyway, in response, it is possible to apply these registry values without using a .reg file. The script below should do it. (Obviously needs to run as a logon script).

    reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /d 1 /t REG_DWORD /f
    reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /d "proxyserver:8080" /t REG_SZ /f
    reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyOverride /d "10.0.0.*;<local>" /t REG_SZ /f

    Thank you, Problem solved as far as I can tell. So far all stations have been gaining internet access using the solution above.
