Very funny! I guess is this more of a universal (tech) experience than I had realized: my friends and I spent a lot of time in high school griefing each other with `net send` (and the other `net`) commands.

My memory is fuzzy at this point, but I vaguely recall being able to change others' desktop backgrounds with a remote client. That produced a lot of entertainment value.

A classic at my high school was taking a screen shot of the desktop with icons, setting it as the desktop background, then hiding all the desktop icons.

Bonus points if you could get the teachers machine

I rotated the screenshot to be upside down, set it as a background and then rotated the whole screen on Display settings. So that the background would be on the correct orientation but the mouse cursor and everything would be reversed.

Good times :D

The favorite prank played on me was coworkers changing my wallpaper to a "funny" picture, then renaming *.jpg to *.old and replacing the original *.jpg's with the same "funny" picture. So when I went to change my wallpaper back, it seemed like it didn't work. Harmless (mv *.old *.jpg, slightly more complicated, obviously) and funny!

Yeah, we played around with net send as well, I'm pretty sure you could also shut down other computers with either a net command, or with the shutdown command itself.

We found a way to circumvent the way they prevented third party apps from running and spent hours just playing AoE2 in the "study" hall.
