Be aware that....if they are using a recovery CD or the Windows CD that came with the PC...
Description of the Windows XP Recovery Consolehttp://support.microsoft.com/kb/314058After you enter the number for the appropriate Windows installation, Windows will then prompt you to enter the Administrator account password.
Note If you use an incorrect password three times, the Windows Recovery Console quits. Also, if the Security Accounts Manager (SAM) database is missing or damaged, you cannot use the Windows Recovery Console because you cannot have correct authentication. After you enter your password and the Windows Recovery Console starts, type exit to restart the computer.
When you use Windows XP Professional, you can set group policies to enable automatic administrative logon.

But be careful funny things can happen..
" The issue was that I had upgraded for OEM XP Home to XP Professional. I tried running the XP Professional console and it did not recognise the password due to the original XP OEM Home install which encrypts the password in a different way. I tried the recovery console on the orginal Home CD which worked. There is a microsoft case for this out there somewhere."
