I think some people are getting confused in this thread.

He is asking how to reset the Administrator password that is created during the installation of XP - not the paswords for the accounts that are created after the install. 2 different things.
You can reset the password of any user accounts but the Admin account that is made during set up will still have the same password you gave it.

The way to reset this is to log in to a user account that has Administrator privilages, then go to your run prompt and type "control userpasswords2" in to it (without the ") then press enter.
In the window that opens up highlight the Administrator Account - this is the one that is created during set-up, then click "reset password". Enter a new pasword. Done!

Notice in the pop up window all your user accounts you have created will be listed , bute there will also be an account named Administrator. This is the account you are confusing with your user accounts.

You need to be logged into an account that had admin rights to do this however.
