When I was 12, I found out about `shutdown /i`, which opens up a GUI where you can enter target IP addresses.
Obviously I had to try it out in class. Each computer room in school had its own IP range, so it was easy to target all PCs in the current room.
At the end of the class, I shut down all PCs - it worked!
I told a friend how I did it - of course he had to tell the others in class.. so the war began and everybody shut down their neighbors PCs!
We then invented "defense scripts" in batch, which basically ran `shutdown /a` in an infinite loop to cancel any shutdown requests.
In the end, the administrator disabled the shutdown command - the official reason was potential harm we could do concerning A-levels.

Good times.
