    This does not repro on my XP Pro system. When I lock and unlock the
    system, it creates events in the security events IF I have logon
    auditing enabled. I haven't had time to test against Windows 2000.
    
    And, BTW, if someone already knows your password, this should be the
    least of your worries.
