    Is it just your account or is it random accounts throughout your domain.  If it is just your account I'd start with this

    Link to the account management tools at the bottom of that blog.  Did you recently change your PW.  Any services using your account.

    If it is random accounts throughout your domain then that could be malware/conficker.

    oh wow ok 300 random accounts being locked, ok since they are all not being used on services.  Start by scanning systems for malware

    I'm not saying it is conficker  but that caused a lot of these issues last year.

    You are going to have to put a firewall on your network to stop outside forces from attempting to login to accounts inside your domain.  If you have a malware problem you have a big job ahead of you.

    I had the same account lockouts in my network and it was caused by the Kido virus. What i did was identify the system from where the lockouts were originating from, using our log management tool. Then temporarily block the access for that system or remove it from LAN and scan for viruses.
