You work as an enterprise administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2008. Half the client computers run Windows XP Professional and the rest run Windows Vista.
Domain.com has its headquarters in Seattle and branch offices in Dallas, Phoenix, Miami and Chicago. At every office an Active Directory site with one domain controller is installed. All domain controllers at the Seattle office is configured as Global Catalog Servers. You receive an instruction from the CIO to ensure that the Universal Group Membership Caching (UGMC) option is deactivated at the branch office level. You thus need to identify the appropriate level where this should be deactivated.
