Group Policy not applying for a few users
Having a problem at the moment where some users, around 2 out of 50, aren't having group policy settings applied. I have recently installed new PC's in each classroom running Win 7 Pro, compared to using Win XP on the old machines. There were no problems with this on XP. One of the settings that arn't applying is the proxy settings, so these users can't access the internet so it's of high importance I get this fixed. The wallpaper that's set in GP doesn't seem to be applying either, but when the policy is set to that machine, the wallpaper turns black instead of the default one so it must be receiving something.
The proxy settings are set in the default domain policy, and when I run gpresult /r on the PC logged in as the affected user, I can see that the policy has been applied. I then tried creating a new policy just for the proxy settings which still didn't work but gpresult again shows the policy has been applied.
