RE: Messenger service abuse (from inside the network)

I am the Network Services Manager for a K-12 School District with 2000 users.  First, we cannot beat students no matter 
how much they deserve it.  ;)  I assume you have your computers in nice little OUs.  I would assume the students use 
lab and media center (library) computers typically.  Why not use a group policy to disable the MS Messenger Service on 
those machines.

        Hello list.
        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).
        
        Best regards
