Same series of events happened at my school.

1. Discover net send

2. Discover net send *

3. Get in trouble for using net send *

The next step was discovering telnet and the schools smtp server.

Spoofing email addresses and sending prank emails via open SMTP gateways was fun. Pretty much all smtp gateways were open back in those days.

Same here. However we discovered that the windows service "messenger" had to be re-enabled on the target machine to make this work again. So we'd sneak into a gullible person's computer, log in (each one of us was an admin, yay!), run "net start messenger" and were back in action!
