We have an Active Directory domain that is at functional level for "Windows2008Domain" so it is at Windows Server 2008 fuctional level.
All of the writable domain controllers are Server 2008R2.
Can we deploy a Server 2008 RODC to one of our remote offices?
We already have the server, it is up and running, but not as an RODC. Although the functional level (or domain mode) is set for 2008, some of the schemas are listing level 47 (Level for Server 2008 R2). Would this possibly cause issues?
The domain was previously Server 2003 functional level, once we dumped the 2003 DC, we upped the Functional Level to 2008, thinking that we could then use the existing Server 2008 machine to be an RODC. We have NOT run adprep /*anything*, but were wondering if we needed to up the OS of the older server system.
Secondary Question: If we cannot do this because of the schema level issue, is then a Server 2012 RODC on a Server 2008 R2 domain then a possibility? Or should we demote one of the 2008 R2 servers to an RODC and then use a new 2012 server as a DC in a 2008 R2 functional domain?
Thank you for your time and answers.
