    Folks,
    
    If you change a user's password in XP Professional you lose access to
    all the 'secrets' stored in the profile, as they are protected using a
    function of the user's hashed password. Secrets being any sensitive data
    protected using the appropriate CryptoAPI functions. This can include
    EFS certificates and associated private keys, Passport information, and
    credentials to use when surfing to password-protected web-sites. I
    suggest you read the XP Resource Kit for further details.
    
    One thing to note: a local user account (not a domain account) can
    create a disk to backup their passwords (not secrets). This disk can be
    used in conjunction with several hacking tools to overcome the problems
    associated with a reset of a user's account password. The disk should
    not be stored with a laptop or near a user's desktop!
