Firstly, ensure no-one can trace this back to YOU, but you could try this:Write a .BAT file that says "Oi, get back to work you!"
Use BAT2EXE (on SIMTEL somewhere) and convert the above .BAT into SOL.EXE.
Write a KiX script that takes the output of a NET VIEW command and sends a copy of your new SOL.EXE to the admin$\system32 of each computer parsed from the > of NET VIEW.
