Read Only Domain Controllers are a great option for sites with less then desierable security. When deploying RODCs, one thing to consider is a local administrator. Unlike traditional Domain Controllers, RODCs areable to have a local administrator. These local administrators do not have Domain Administrator rights. They can only work on their RODC. Some of the tasks they can perform are:
· Install hardware devices, such as network adapters and disk drives
· Manage disk drives and other devices
· Install software updates and drivers
· Stop and start Active Directory Domain Services (AD DS)
· Install and remove other server roles and features
· View logs in Event Viewer
Manage shares and other applications and services
How do you delegate the local administrator role for an RODC? If you are using the wizard, you can delegate this role to a user or group on the Delegation of RODC installation and Administration page. (See below)
You can also delegate after installation in one of two ways. By opening the RODC account property, you can specify the local administrator in the Managed by tab. Click Change and select the user or group you want to delegate to.
You can also do it using the commands ntdsutil local roles or dsmgmt local roles command. Delgation via command line is not recommended because it is stored locally, not in Active Directory.
