Specify a Domain Controller
Applies To: Windows Server 2008
To specify a domain controller
In the Group Policy Management Console (GPMC) console tree, perform one of the following actions:
If you want to specify the domain controller for a domain, double-click the forest containing the domain of interest, double-click Domains, right-click the domain of interest, and then click Change Domain Controller.
If you want to specify the domain controller for a site, double-click the forest that contains the sites of interest, right-click Sites, and then click Change Domain Controller. In the Look in this domain drop-down list of the Change Domain Controller dialog box, select the domain in which the domain controller resides.
Select the domain controller option from the Change Domain Controller dialog box and click OK.
Additional considerations
All operations performed in a domain on Group Policy objects, security groups, and organizational units use the domain controller that you specify for the domain.
All operations performed on links to sites use the domain controller that you specify for the sites.
