How to trace and diagnose account lockout in AD?

An account gets locked out if the bad password count exceeds the threshold limit. If account lockouts are not identified and fixed immediately, they could cause a great deal of problems. Use the following steps to identify locked out accounts:

Step 1 - Search the domain controller possessing the PDC Emulator Role

<get-addomain→.pdcemulator <domain name→

Step 2- Search for Event ID 4740

Go to the event log viewer of the DC holding PDC emulator role and in its security logs, search for Event ID 4740.

Step 3 - Apply appropriate filters

You can apply filters in case you want a more customized report such as looking for lockouts that happened during the last one hour, to find the recent lockout source of a particular user.
