Well, later on she writes that she pulled the network and for now that's her solution.
Now, by saying "achieve" I don't mean any immediate goal such as prohibit the use of the internet or the home PC. The point is, why would the OP want that? To what purpose? Granted, this is a technical forum and she came with a technical question, but I still don't see how locking the home PC would prevent her daughter from using computers in general - will she also lock her daughter at home and not let her go to school?
I repeat - there is no 100% bulletproof security tool to completely lock up a PC. The only thing that can be achieved, is to set up security measures which would be above the daughters skill level. But if she's really determined, she could learn and eventually bypass that as well. Or if her goal is not some particular data on that very PC (and it looks like it's not, judging by the network-pulling solution), she can just go some place else.
That's why I think this is a parenting issue more than a technical issue. Prohibitive measures just drive children and parents further apart, which in my opinion is counterproductive. But I guess I will stop here.
