The school that I went to had an extreamly interesting trick, and I am still not completely sure how they did it.
All of the computers seemed to be networked to one server. And I do mean ALL. Every machine in the school. The reason that I say this is because all that you had to do is sit down in front of any computer in the school, type in your Username/Password, and all of your files where in place. You couldnt install anything, they where not running any sort of security, and even if you changed the wallpaper it was changed back between sessions. As far as I know, that school never had a single security problem. Ever.
Oh, and the school had mixed classrooms. Some running Windows, others running Mac, depending on the needs of the classroom according to software. Using photoshop in a web mastering class? Mac. Running CAD? Windows. No matter what, you could log in to any machine with the same information, and your files (from any class) would always be where you expected them to be.
I have a few theroies as to how they did this, but I have never been able to replicate the results on Virtual Machines so I am not completely sure.
Any ideas?
P.S. I dont mean to hijack the thread BK_123, this just reminded me of that setup and I have been wanting to ask this question for a while.
