Read to the end!

my page didn't load the images (or whatever) in any kind of timely manner, so i bailed on it before they loaded. was there more than just the one pop-up?

Pretty sure there aren’t images, and you received, but were unimpressed, by the outcome.

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

The hidden copy of UT resonated deeply with me. We spent many hours playing Doom and Quake in the high school computer lab when the teacher was out of the room. Every time we were discovered we had to hide it somewhere else.

Had the same experience at my school, but IT was much slower. net send * worked for weeks if not months

just wanted to say I enjoyed the alert() at the end

It was an absolute free for all when windows machines started to be plugged into campus networks.

The prankster's evolution generally went from net send to NetBus and then to Back Orifice in those days as the tools rapidly made such tomfoolery a point-and-click affair. Interestingly many of the features in these early Windows prankster/hacking tools heavily shaped modern day remote administration / MDM software. I actually remember BO being used as a proper remote management tool in some situations.

I remember doing this! I remember graduating to the more nefarious “Microsoft’s IPX implementation responds to broadcast pings”. It might have been this CVE: https://learn.microsoft.com/en-us/security-updates/securityb...

Luckily I went to a school that believed in redirecting the (endless) time and (boundless) energy of obnoxious nerds like me, and I spent far more time helping out than breaking things. Or at least I hope… the long tail on the IPX ping was pretty painful to stop.

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.

Heh. If you used the underlying windows api calls, you could spoof the sender. Something I discovered when I did just that, in the Windows 2000 days.

Combine it with a for loop and you could generously message everyone on the LAN with little effort.

There's a reason why everyone around me turned off the net service after a while...

Best way to hide files on Windows: \$Recycle.Bin :)

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
