You are the network administrator responsible for testing and deploying new service packs for Windows 2000. Your forest has two trees, with four domains in each tree, as shown in the exhibit. For the testing of each service pack, you plan to deploy the service pack to the support.IS.contoso.com domain and the support.IS.litware.com domain, but to no other domains. You plan to use a Group Policy to configure and administer the service pack package. You need to minimize the complexity and administration of the service pack package, and to minimize network traffic between the domains. You create a Microsoft Windows Installer package for the service pack. What should you do to configure the Group Policy?
