Password policy is a basic security setting that any administrator uses. In the Active Directory environment, password complexity settings and account lockout settings can be applied using GPO settings located at Computer Configuration | Policies | Windows Settings | Security Settings | Account Policies. Before Windows Server 2008, there was only one password policy and account lockout policy setting that could be applied to the users. With Windows Server 2008, Microsoft introduced fine-grained password policies. This allows administrators to apply different password and account lockout policy settings to individual users or groups. This allows you to protect privileged accounts using strong policies than regular user accounts. This feature continued with every AD DS version after 2008 and is available with AD DS 2016 as well.
