Freezing lots of Computers at Once with Message...

if you have ever wanted to freeze all of the computers in a network (such as at work or school), here is your chance. This can be a hilarious prank, but be aware that some people might get upset when their computers are all frozen. (Be careful! If you don't have permission or ownership, charges can be filed against you. This prank is technically classified as a Denial of Service attack. I will not be responsible for anything you do with this information.)

This mass freezing will work by having one or more "host" computers send hundreds of thousands of pop-up messages to everyone in the network. Every time you try to click on something, more pop-ups have gotten in the way, soon freezing the computer. When all of the computers are shut off and rebooted, it starts all over!
Have fun!

Step 1: Write the Script

Frist  we will write the netsend script. This will send a message to all of the computers on the network. You can either do batch or VBS on this, but batch is more intimidating. Here is the code that you need, and remember to save it as anything.bat (the part before .bat can be whatever you want).

open notepad

copy this script and paste it in notepad then save it as  anyname.bat

 

@echo off
:start
net send * messagehere(type what you want to appears on victim pc)
goto start

What this will do is send a pop-up message to all of the computers in your network, and then loop back and do it again. It will go as fast as possible, taking up all of the CPU usage. That way, no one could stop the program (as that takes up CPU) without turning off the machine. As all of the network's computers are going ballistic with pop-ups, no one will know which one is causing it (especially if you launch this from two computers in the network, as they would both be causes but look like victims).
