2) To stop it from happening, you'll need to either:

     a) Stop them from being administrators on their machines
          (*That's* not going to happen - just google 'nordahl
password' to see why)

Not so hopeless as you may think.

First, set the BIOS on each machine to use the hard disk as the primary
boot device (assuming you're booting from disk) and disable all other
boot device selections.

Second, set a supervisor password on the BIOS so that no unauthorised
changes can be made.

Third, physically secure the machine so that cannot be opened without
permission to prevent any manual resetting of the BIOS.

Booting tools from live CDs can circumvent any OS-level security you may
have implemented. This would force all users into the OS before any
access to the machine can take place, and maintains the integrity of
your security policy.

This isn't 100% guaranteed, but it will deter pretty much all of the
casual problem users.

Just my $0.02.

1) To enumerate shares on student machines, one tool that I've found
useful is Angry IP  Scanner, found at

plugin for it, if you're scanning from a Windows box.
