IE, Disable 'Automatically Detect Settings' Via GPO

Hi guys,

We have recently been having a small problem with IE, whereby the 'automatically detect settings' check box will get ticked - resulting in our users not being able to traverse our proxy server.

I use the User Configuration > Policies > Windows Settings > IE Maintenance > Connection to set up our proxy settings, however I can't see an option to explicitly disable the 'automatically detect settings' check box.

Is this located somewhere else in an admin template, or am I simply missing an option that is right in front of me?

Thanks.

Glen
