Account Frequently Being Locked Out of Active Directory

We have a 2012 terminal server that about 30 users access daily. One user is having his AD account locked out multiple times a day.

We've checked the event viewer and security logs, and absolutely related to the lockout appears.

Any help would be greatly appreciated!

Hi

Use eventcombmt to search the lockout. In the text column give the user name and select your PDC server. check the server event id is 4740,4771,4772,4773,4776
