Back in the XP era at my school you could type in the cmd line "netsend (local IP) (message here)" and a screen would pop up on their computer with the message and all they could do was click "Okay" so my friends and I would message each other that way since each computer had it's IP on it with sharpie. I was messing around with it like usual and one day I came across the "netsend all" function and I ended up typing "hello" and hit enter and it popped up on every machine in the room instantly. After further investigation I found using /dir that I sent it to every computer in the entire school district lol. About two weeks later one of my friends not knowing it was me helped the school locate me as being the culprit and I got a nice talking to because I could have caused mass panic with the right message. The vice principal eventually got curious how the hell I did it so I just told him how I was using Google because I was also curious and I tried it out not knowing what would happen, ended up getting threatened with not being able to walk at graduation if I did it again but that was it lol, windows used to be fun. This was back in 2006 so everything was still slightly crazy from 9/11 so I'm surprised more didn't come out of that

I did the same thing and got kicked out of computer class. They made me use the computer down the hall that had no network access lmao.
