Proxy settings keep being applied

[pandster]

Our Local Education Authority has recently changed our proxy server to be transparent. As a result, any machines we have around the school which have proxy settings in place cannot access the internet. Problem is, our group policy has an enforced restriction on users changing proxy settings (some of our kids are too clever by half!). We can change the following keys in the registry:

HKEY_CURRENT_USER\software\microsoft\windows\currentversion\internetsettings

proxyenable

and

proxyserver

However, there seems to be some kind of hangover registry setting which applies the proxy settings when the user logs in. We can find this key in

HKEY_USERS\%SID%\*same key as above.

Logged in as local admin, I've amended the Default user NTUSER.DAT file to take out the relevant registry entries, I've even amended the NTUSER.DAT file in the specific user profile, but it still manages to find the keys and apply them when the user logs in. Gibbering wreck on the horizon. Any ideas?

Can you set an enforced group policy of "no proxy"?

Group policy seems to be deliberately ignoring any settings we apply regarding proxy configuration. I'm just reading a related post regarding IE Maintenance settings not being applied if folder redirection is enabled.

 

EDIT: Tried that. Didn't work.

Sorted. Ran DCGPOFix on Default Domain Policy.
