This exercise walks you through the steps you need to take to configure a domain controller as a Global Catalog server.
- Open the Active Directory Sites And Services administrative tool by clicking Start > Administrative Tools > Active Directory Sites And Services.
- Find the name of the local domain controller within the list of objects (typically under Default First Site Name ? Servers) and expand this object. Right-click NTDS Settings and select Properties.
- In the NTDS Settings Properties dialog box, type Primary GC Server for Domain in the Description field. Select the Global Catalog checkbox, then click OK to continue.
- If the box is checked, then this domain controller contains a subset of information from all other domains within the Active Directory environment.
