Not recognizing logon password

I had a usb device that wasn't recognized. the manufacturer said to remove and reinstall sp2. Now  when I put in the password it gives me  "the system cannot logon due to the following: the parameter is incorrect" and when I put in an incorrect one, it gives me the normal "did you forget..." I also remove the hot fixes.

I have tried to safe mode, last known good configuration.

Please help.  Thanks

I don't like the sound of this at all. Also I don't see what on earth the guy was trying to achive then you were asked to un-install and re-install SP2. Try logging in with the administrator password and use system restore. If this does not work and you can't boot into safe mode you may have to do a clean install.

the only choice I have on the desktop is me. How do I get to the admin choice?

You need to hit Ctrl+Alt+Del twice at the Windows Welcome screen. This will bring up the standard XP (domain-style) logon box.

Logon using the Administrator username and password.

(if you don't know the Administrator password - look here: http://home.eunet.no/pnordahl/ntpasswd/)

Then - logon, and reinstall SP2.

If that doesn't help - you may have to do a repair install of Windows.

Your error sounds like the security policy on your computer is confused, to say the least.

You may not be able not to recover this without at least a repair install.
