With a decentralized GPO approach (see Figure 10-9), the goal is to include a specific policy setting in as few GPOs as possible. When a change is required, only one (or a few) GPO(s) have to be changed to enforce the change. Administration is simplified at the expense of a somewhat longer logon time (due to multiple GPO processing). To achieve this goal, create a base GPO to be applied to the domain that contains policy settings for as many users and computers in the domain as possible. For example, the base GPO could contain corporate-wide security settings such as account and password restrictions. Next, create additional GPOs tailored to the common requirements of each OU, and apply them to the appropriate OUs. This model is best suited for environments in which different groups in the organiza tion have common security concerns and changes to Group Policy are frequent.
Centralized GPO Design
With a centralized GPO approach (shown in Figure 10-9), the goal is to use very few GPOs (ideally only one) for any given user or computer. All of the policy settings required for a given site, domain, or OU should be implemented within a single GPO.

Implementing Group Policy
If the site, domain, or OU has groups of users or computers with different policy requirements, consider subdividing the container into OUs and applying separate GPOs to each OU rather than to the parent. A change to the centralized GPO design involves more administration than the decentralized approach because the settings might need to be changed in multiple GPOs, but logon time is shorter. This model is best suited for environments in which users and computers can be classified into a small number of OUs for policy assignment.

Group Policy Processing
As mentioned in earlier chapters, planning your OU structure is key to the effi cient application of Group Policy. Every additional policy that you apply increases the number of settings that the individual computers must evaluate. Planning your organizational structure so that you can apply as few group poli cies as possible to only those containers that require them is a key to improving startup and logon performance. You might even decide to create OUs for the pur pose of applying a specific Group Policy. For example, if you have several com puter accounts that require a specific configuration that is unique to only those systems, you may find it more efficient to create a separate OU in order to handle that special configuration.
Planning Administrative Control of GPOs
When you plan the Group Policy settings and GPOs to be used in your organization, you should also plan who will manage them. The appropriate level of administrative control can be delegated by using a centralized, decentralized, or task-based adminis trative control design.

Group Policy Planning Strategies
10-27
Centralized Administrative Control Design
In the centralized design, administration of Group Policy is delegated only to top-level OU administrators. In the example shown in Figure 10-10, top-level OU administrators have the ability to manage all GPOs in the domain. Second-level OU administrators do not have the ability to manage GPOs. You can accomplish this by assigning Full Con trol permission to top-level OU administrators. This design is best suited for organiza tions that want to consolidate the administration of group policies.

Decentralized Administrative Control Design
In the decentralized design, administration of Group Policy is delegated to top-level and to second-level OU administrators. In the example shown in Figure 10-11, toplevel OU administrators have the ability to manage GPOs in the top-level OU. Secondlevel OU administrators have the ability to manage GPOs in their second-level OUs. You can accomplish this by assigning Full Control permission to top-level OU admin istrators for the top-level OU GPOs and Full Control permission to second-level OU administrators for their second-level OU GPOs. This design is best suited for organiza tions that delegate levels of administration.
