How to crash a PC running W95 on a IPX(or TCP) network.

At my high school, we have a network of PC running W95 with a master PC(A gateway between the Net and IPX). I hate the technician, He's stupid, incompetant, anti-mac and ugly. So my friends and I wanted a revange. So we took a computer, we launched 15 "command.com" and typed: ping -t -l 500 IP.of.the.host in each of the command.com windows. After 5 to 8 minutes, the server started to crash. So the technician rebooted the PC and the PC kept crashing forever.  It was so funny! 
A great thing to do:
At my high-school, the tech. just come on wed. and mon. so I try to crash the PC just when the tech. isn't in the school. The school call the tech. and tadam no probs!  So the school called the tech. for nothing. Yeah!

The only side-effect is that the admin. don't see(virtually, of course) you on the network.
