I want to remotely block all internet access to students in a classroom from the teachers machine. So they can work on local programs and not surf and play games.
As instantly as possible. Be able to instantly turn it back on again.
Switching proxy by policy is to slow and requires a restart of internet explorer.
Possibly blocking port 80?
Using vbscript by preference. Or visual Basic. Very simple on off button required. No comercial programs must be free.
Ideally click on station name and instant bann of internet. Like a traffic light stop and go.
