    This is a little better since it gives you logon types.


    There is quite a lot of info out there on failed logons. What I would
    like to know is when someone locks their machine. That doesn't seem to
    trigger anything in the event logs. But I don't want to audit every
    object access. Any ideas?

    Subject: Event Log messages for failed logon attempts

           I am currently working on a small script that will parse the
    event logs of a Windows NT/2000/2003 domain controller looking for
    failed logon attempts. I am currently aware of event log message 529. I
    believe that I have been able to generate several other error messages
    for failed logon attempts depending upon what a client is using to
    authenticate with (ex. Kerberos, NTLM, etc...). Does anyone have any
    other input or articles that they would suggest as the only KB article
    that I have found so far was 299475.
