    Regarding all the mails regarding Kerberos and NTLM, I would like to add one
    additional remark.

    I see that one important feature is also missing in the Windows 2000/2003
    environment: the ability to audit what type of authentication is used by the
    clients.

    Say I want to eliminate NTLM V1 & Lanmanager.
    If I'm able to audit all the users that still use thes types of
    authentication protocols (Win9x, Samba, NAS appliances), I can warn them and
    take appropriate action before actually shutting down the protocol. However
    at this moment I'm unable to see what type of logon-requests are still used
    by the clients, so I'm unable to contact the persons and warn them before
    actually upgrading the security policy.

    So I would be nice to be able to audit which of the users/machines is still
    using the Lanmanager or NTLM V1 authentication protocol to be able to safely
    disable these protocols without causing a lot of problems the day you
    disable them.

    At this moment you can only audit who is using Kerberos and who is using
    Lanmanager/NTLM V1/NTLM V2. The different levels of NTLM/Lanmanager cannot
    be audited, so it is therefor impossible to see who is still using NTLMV1
    and Lanmanager in a Windows 2000/2003 environment.

    Regards,

    Frank
