Windows 2012 - Group Policy Management

Create a new group policy.

Windows 2012 - Group Policy Objects

In our example, the fourth incorrect login attempt will block the user account.

The system will automatically configure the lockout duration time to 30 minutes.

GPO - Account lockout duration

Access the item named: Account lockout duration.

Set the number of minutes a locked-out account remains locked.

GPO - Account lockout duration minutes

In our example, the account will remain locked for 5 minutes.

After 5 minutes, the account will automatically become unlocked.

The system will automatically configure the lockout counter to be reset after the same amount of time.

If the account lockout duration is set to 0, the user account will remain blocked.

To save the group policy configuration, you need to close the Group Policy editor.

Only when you close the group policy editor, the system will save your configuration.

The default domain policy already has a configuration to the account lockout policy.

The default domain policy is set to never block a user account.

Before enabling your account lockout policy, you need to disable this part of the configuration on the default domain policy.

GPO - Default domain account lockout

Congratulations! You have finished the GPO creation.

Tutorial – Applying the GPO to force the account lockout
