Block internet to Internet Explorer 7 on Vista
At the moment I've got a banned internet group which reads a group policy that uses a dummy proxy. This works, however when the user sees this page can not be displayed, the user can click the link on the page that says "Diagnose Connections problems". As we have wpad in place when the banned user clicks on the diagnose link internet explorer ticks the "Automatically detect settings" box even though this is disabled in the banned policy. This then allows them to browse the internet as normal.
We're tried to find a group policy for this and even installed the latest admin templates no joy.
The reason we're tried to avoid banning the iexplore.exe is because if the student is using Dreamweaver and wants to test their page.
