Hi,
Currently sdudying for 70-640 and have a question to which i can't find an answer on google, not one that is clear to me anyway.

I have 10 DC's. 5 are writeable 2008 servers and 5 are RODC 2008 servers. All are domian controllers.

The forest and domain run at 2008. If I add a RODC 2008R2 domain controller do I need to run either domain prep or forest prep?

Thank you

Prepare the forest and domains. There are three adprep commands to complete and have the changes replicate throughout the forest. Run the three commands as follows:

 Prepare the forest by running adprep /forestprep on the server that holds the schema master operations master (also known as flexible single master operations or FSMO) role to update the schema.

Prepare the domain by running adprep /domainprep /gpprep on the server that holds the infrastructure operations master role.

  If you are installing an RODC in an existing Windows Server 2003 domain, you must also run adprep /rodcprep. For more information, see Prepare a Forest for a Read-Only Domain Controller. For more information about how to resolve possible errors when you run adprep /rodcprep, see Adprep /rodcprep can have an error if the infrastructure master for an application directory partition is not available.
