    Really it could be anything - user stupidity, malware, hack attacks, cached credentials, poor password policies....

    Tell us a bit more about your network - what OS, how many DCs, how distributed to start with
    What do the event logs show you - where do the lockouts come from (internal or external, just a few clients...)

    When you say users are all getting locked out, do you REALLY mean all users are locked at the same time?

      Yes, All users are getting locked. It is happening in one of my colleagues company. They are using windows server 2008 R2. Single site and single domain controller. Total 200 users.

        Malware on the DC?

        What about the event logs (on the DC)?
