To use Active Directory Sites and Services to force replication of the configuration partition
to an RODC
1. Open the Active Directory Sites and Services snap-in (Dssite.msc).
2. Double-click Sites, double-click the name of the site that has the RODC, double-click
Servers, double-click the name of the RODC, right-click NTDS Settings, and then click
Replicate configuration to the selected DC.
3. Click OK to close the message indicating that AD DS has replicated the connections.
