Like planning your Citrix Policies, you must also plan how and where your Active Directory GPOs will apply. This is done by assignment within the OUs, WMI filters, and inheritance of group policies. Active Directory group policies are stored with the domain controllers and managed using the Group Policy Management Console, which can be performed on the domain controllers or another server with the proper roles and features.
Every Active Directory environment has group policies. With Citrix deployments, there are some necessary settings that are not available through Citrix Policies. When this happens, these settings will need to be applied locally or through Group Policy. Obviously, the Group Policy application is preferred for its reusability and consistency.
