Getting rid of Admin Passwords

[Ken Poppers]

I have a Powerbook G4 using Panther from work,  I do not have admin 
access, so I can't connect to the internet (other than my employer's 
web site) software update, etc.  I want to kill off the admin and 
convert it to a single user.

I was thinking of restarting the computer as a firewire hard drive and 
grabbing all the offending files and trashing them, but I don't know 
exactly which ones to get.  Any ideas?

The computer was paid for by a grant, not by my employer, but tech 
services imaged it as if it is an "on site" computer, not one for home 
use.

Thanks
