I am working in a small school with some really tough students. One teacher with ten computers in his room wants to prevent students from logging on to a computer until he gives the okay. This is to prevent the computers from becoming a distraction while he is trying to get them to do something else. He would like a way to lock and unlock all ten machines at once as needed. How can this be done–without buying expensive software?
A few details:
55 Computers(that includes the ten in question) on one domain, one forest
Windows 2003 R2
Windows XP SP3
