Yes... we are all aware that if you have ownership (physical possession) of the box, that you can get into it. A number of ways.
By the same token, as a consultant, I charge quite a bit of money to companies who, for example, have had a disgruntled administrator leave and take passwords with them.
Of course, there is an inherent danger of doing such, since you're bypassing all of the windows security, and it's not something that I would suggest someone try for the "first time" on a mission critical server.
But, all of that aside, any kind of hacking / compromising discussions (whether it be for the forces of good OR evil) is not what Tek-Tips is about.
And, as a final note, I would suggest that persons who find themselves in a situation where they have to compromise security for a legitimate purpose should probably contact someone who has experience in it. I know that I messed up a couple of machines years ago by not having a firm understanding of what I was doing.
Just my 2¢
