Enforce

Enforce: In Group Policy Management console (GPMC), to force the Group Policy object (GPO) links of the parent container to take precedence over the GPO links of the child containers. By default, the GPO links that are closest to the user or computer (links to the child container) have higher precedence than GPO links higher up (links to the parent container). Enforcement causes GPOs that are linked in parent containers to take precedence instead. In operating systems in the Windows Server 2003 family without GPMC, No Override is used instead of Enforce.
