To change the reference domain controller

1. On the Tools menu, click Configure Ultrasound.
2. Under Monitored FRS replica sets, choose the replica set for which you want to change the reference domain controller.

   If you have recently made changes to the FRS topology and those changes don’t appear in this dialog box, click the Sync Topology button to force a manual poll of Active Directory information for the selected replica sets

3. Under Ultrasound Reference Sources, next to Reference DC, click the Change DC button.
4. Under Change Ultrasound reference DC to, click the domain controller to act as the reference domain controller.
5. Under Apply change to, click one of the following:
   • Current selected replica set to change the reference domain controller for only the selected replica set
   • All replica sets referring to the current DC to select a new reference domain controller for all replica sets that use the server shown in Current DC as a reference domain controller. Choosing this setting is useful if you are decommissioning the current domain controller and want a number of replica sets to use another reference domain controller that is common to those replica sets.
   • All replica sets in the current domain to use the newly selected reference domain controller for all replica sets in the domain.

For information about changing the frequency at which the reference domain controller is polled, see To change the reference domain controller polling schedule.
