I found a free bit of software to do this a few years ago but the I.T. department at my college delayed and back-pedalled for long enough for me to give up on getting it installed.
Have better access to permissions now but can't find the damn software anymore, does anyone have any tips? The one I found involved a quick install on all the machines on the LAN and then they could be disconnected from the net by one master machine... handy to help my students focus at times (and when I'm out of the class).
