I have an NT 4 domain, and would like to install W2K Pro desktops with NT 4 group policies. This is a high school, and the little darlings seem to have a contest going to see how many computers they can make non-funtional before the end of the year.I have my own goals. One, I need to prevent the installation of software by students but seem to be unable to do so in the group policies. I have tried purchasing software that restricts the students, but the software causes as many problems as it solves and the students have figured out how to get by it anyway. Two, with 800 students, I don’t want to store local copies of profiles on lab computers because of disk space. NT 4 roaming profiles do not give an option to delete local copies of profiles. Three, I need to keep traffic to a minimum because of the share numbers of computers on a 10BT network. Any suggestions or how to’s would be much appreciated.
