What should you do to delete all the unknown groups from the membership list for the domain local groups?

You are the network administrator for your company. The company consists of two subsidiaries named Contoso, Ltd., and Fabrikam, Inc. The network consists of two Active Directory forests. The WAN connections that connect some domain controllers are unreliable. The domain and trust configuration is shown in the Network Diagram exhibit. (Click the Exhibit button.) You create shared folders on Windows Server 2003 member servers in both forests. Some of the shared folders are accessible to users from both forests. For each of the shared folders, you create a domain local group. You add global groups from domains in either forest to the domain local group. The Fabrikam, Inc., division is sold to a different company. You delete the trust relationship between the two forests. You notice that after the trust relationship is deleted, the membership lists for some of the domain local groups are no longer accurate. When you view a membership list, it contains entries without user-friendly names. A sample is shown in the Membership List exhibit. (Click the Exhibit button.) You need to delete all the unknown groups from the membership list for the domain local groups. You want to achieve this goal by using the minimum amount of administrative effort, and without modifying the access to resources for users in the contoso.com forest. What should you do?
