I Need help with a WMI filter
We have had a member of staff come in and discuss the new system for coursework on the computers in a controlled environment. The students can't have access to the internet whilst working on their coursework apparently, so we need to apply a policy which does not give the students internet settings in certain lessons (ie. at certain times of the day/week). I was thinking that maybe we could apply a Group policy that is configured with a WMI filter for certain times, but the only problem is that I can't find any examples of this.
Does anybody have any idea of either what the WMI filter would be, or another way to enforce this rule?
