Go get NTPASSWD (see google) and reset the admin password. Remember this is free software and is SIMPLE to use. Just answer the questions and reset the password. Plenty of documentation out there.
Now repeat the above but for name and password use administrator and for the password press the return key.
Hope this gets it done.

PS. I can't find the make, model of this machine. Might matter, might not.
Following the below directions I get as far as #3, but instead of asking about language I get a screen saying "other user", I have no other choice but to hit Enter, which brings up two boxes asking for "User Name" and "Password". I put in my username and I never set up the computer with a password so I just hit enter. This is the message I receive "The specified domain either does not exist or could not be contacted". I am the only user account on the computer and have the administrative rights.
Any suggestions welcome!
