My manager got issue with his user account locked out every random time so i have to unlock it every now and then. what is the best way to troubleshoot this issue ?/* Server Support Specialist */

Hi Albert, Please follow the below steps. When the account is locked out, please login to any one of the DC and execute LockoutStatus.exe to find from which DC exactly this account is getting locked out. Once you get the DC name, use eventcombMT.exe tool and check from wich machine this account is getting locked out. Once you get that details it will be easy for you to check the issue. Please find below possible causes for account lockout Mismatch of password.Scheduled tasks and persistent drive mappings that have stale credentials.There might be any applications services which uses your id and password too. So change your password in that service.The batch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention.Disconnected Terminal Service sessions that use stale credentials.Stale logon credentials cached by Stored User Names and Passwords in Control PanelUsers logging into two or more computers at once and changing their password on one of them.
