Domain Administrator Account Locked
Greeting,
I have been using MS Account lockout tools to try to determine which client is sending bad password attempts that is locking out the Domain Administrator Account.
i believe i have found the culprit but i do not know how to get it to stop. Any suggestions would be appreciated. here is a section of the log file that has the client information.

4CHail,
This can sound like a suspicious software on the machine. I'd go ahead and have it re-imaged. Just to be sure.

After looking at the Admin account, i noticed there were options to use kerberose des encryption type for this account. Because the log showed the service was krbgt/domain.com i decided to try this option. I have had no more lockouts since making the change.
