Yeah..... I remember doing my collage studies where I had to do some workplace experience at my dad's high school. The computer co-ordinator gave my team the Libeary computer to lock down.
In the end, we managed to lock down every thing..... except if you opened up internet explorer and started looking around the computer, as appose to the internet, you could still edit your *.ini files.
In the end, it did slow down the amount of cyber vandalism that was happening in this school Libeary. All though we all new that there was this really big hole in the security.
This was in 1998.
