Password Protected

A friend of mine password protected a computer in spawn, when he types it in it says it's incorrect.. even though he knows it. He disabled the use of CTRL+T etc, Owner wont be on for a few days and Admin's dont want to touch it. Whats the code i can use to terminate the program and return the computer back to normal with a floppy.

Create a file called "startup" in a floppy and type some invalid code in the file. Then reboot the OS(Ctrl+R).

Invalid code isn't even necessary. A blank startup file in a floppy will do the job.
