You are probably being asked to use a Windows XP admin account. You need to log into your XP Operating Sytem as an admin level user. If you use Ctrl + Alt + Del twice from the logon screen you will be offered a choice of user account and password. The 'Administrator' account itself is not normally seen when logging on. XP probably sets up the Administrator account with a null default password so enter the name 'Administrator' and then put the cursor in the password fields and hit the return key. It is always a good idea to actually enter and use a password, it is also a good idea to create a password reset floppy. If you have any account that already has administrator priveliges that may be uses to change passwords and account names. If all else fails a clean reinstall of the OS will probably get you in as an administrator.
