Link the GPOs to the Domain
Applies To: Windows Server 2008
Use this procedure to link the GPOs that you created earlier to the domain container in the Active Directory hierarchy. Because the assignment of the GPOs is controlled by the combination of the security group and WMI filters, you do not have to assign the GPOs to OU containers.
Linking GPOs to the domain container is appropriate for GPOs that must be used by computers throughout the Active Directory hierarchy. Link GPOs that apply only to a subset of the computers in the network to the OU container that is lowest in the hierarchy but still includes all of the targeted computers in the containers below it.
Membership in Domain Admins is the minimum required to complete this procedure.
To link the GPOs to the domain container
Log on to your domain controller as a member of the Domain Admins group.
Click Start, and then click Server Manager.
The Server Manager console opens.
In the navigation pane, expand Features, expand Group Policy Management, expand Forest: your forest name, expand Domains, expand your domain, and then expand Group Policy Objects.
Drag each GPO in the Group Policy Objects node to the node for your domain container. In the confirmation dialog box, click OK.
