Use a GPO and remove the run line and command prompt options from them. If they can't get there, they can't use it.

I administer a high school network running W2K Pro in an Active Directory domain. The problem is that the users abuse the Messenger service by sending some mischief over the network (furthermore, they even write batch files that repeatedly flood the domain with same text). Is there a way to prevent this, except by changing net.exe's ACL on all machines (or beating the offenders after classes :)? Stopping Messenger service on the workstations is not a solution, as it is used for sending various administrative messages. All students share a common AD account (it would be cumbersome to maintain 300+ user accounts, as most of them use the PCs for short periods only).
