Once GPOs have been created and configured, they must be linked to the appropriate sites, domain, or OU. Before you can link a GPO, you must register and check out the site, domain, or OU. For information on registering Scopes of Management, see Registering objects .
Users with the Link right can link a single GPO with numerous sites, domains, or OUs and link multiple GPOs to a site, domain, or OU. (For more information on setting permissions, see Configuring role-based delegation.)
By default, GPOs affect all users and computers contained within a linked site, domain, or OU. To refine the application of a GPO, see Editing GPOs .
You can also select to restrict the link source to include only policies from specific containers. To restrict linking, see Viewing and editing object properties.
