My user account gets locked out constantly. I ran the MS lockout tools and could see the account getting locked out. I also ran the other tools EventcombMT and found a device with my name on it to be the culprit with an IP address. When I pinged that IP address, it came back with the device and the device name was mine. I looked in Active Directory computers and that device is not a computer listed. My computer is listed with the correct computer name. How do I find this rouge computer that is trying to log on and authenticate; thus locking out my account? I killed the DHCP lease to kick the computer off; but how do I find it?
