I was wondering if anybody has a clever way of temporarily blocking internet access on a group of PCs.
I'm hoping that somebody has been in my situation before and knows a pretty solution. What I have is a school network with 3 computer rooms, and I'm getting requests from the computer teachers for them to
have control over whether the PCs can get internet access or not. What they are looking for is really just an on/off switch for each room.
Is there a neat way of doing this? (Totally disconnecting the rooms not being an option, as they still need access to other stuff on the network)
