If you need to administer a RODC, do it remotely. Don't log on locally to a RODC with your domain admin account or you'll compromise it's security. Instead, if you MUST log on locally to a RODC, create and use a temporary domain user account for that purpose and add this user to whatever security group you have delegated authority for administering RODCs. Delegation of RODC installation and administration is assigned to a group or user when you run the Active Directory Installation Wizard to promote a server to a RODC, but you can also specify a group or user for delegation afterwards by opening the properties of the computer account for the RODC and selecting the Managed By tab.
