A user-defined number of minutes from 0 through 99,999.This policy setting is dependent on the Account lockout threshold policy setting that is defined, and it must be greater than or equal to the value specified for the Reset account lockout counter after policy setting. If Account lockout threshold is set to a number greater than zero, Account lockout duration must be greater than or equal to the value of Reset account lockout counter after. A value of 0 specifies that the account will be locked out until an administrator explicitly unlocks it. The available range is from 1 through 99,999 minutes. The Account lockout duration policy setting determines the number of minutes that a locked-out account remains locked out before automatically becoming unlocked.

If your audit policy is enabled, you can find these events in the security log by searching for event ID 4740. To thwart attacks, most organizations set up an account lockout policy for user accounts: As soon as the bad password count for particular user is exceeded, their Active Directory account gets locked. Each user’s Active Directory account controls their access to network drives and other resources, as well as their Windows settings and computer configurations. Microsoft Active Directory is a core component of your infrastructure, controlling everything from security settings to Group Policy to user authentication.
