Preparing the forest for RODCs

The /rodcprep switch for adprep.exe triggers the preparation of the forest for RODCs. This action only needs to be performed when the intention is to run RODCs in the Active Directory forest:

To prepare the Active Directory forest for RODCs, run the following command:

adprep.exe /rodcprep /forest lucernpub.com /user DomAdmin /userdomain lucernpub.com /password P@ssw0rd 

Replace the value for the domain and the values for the credentials with values that make sense for your Active Directory environment.

The following line at the end of the output indicates the successful preparation of the Active Directory forest for RODCs:

Rodcprep completed without errors. All partitions are updated. See the ADPrep.log in directory C:\Windows\debug\adprep\logs\ <date> for more information.
