I was managing a few labs full of machines used for training on NT4 which meant I was frequently re-imaging and could use effective remote control capability. Back Orifice was, at the time, the absolute best remote admin solution available for free. I could deploy it in the image and then use it to kick off reimage process, reboot, log out a student, or monitor their screen from the teacher's desk to share on the attached TV. It really was a handy tool for remote admin tasks.
