I'm having trouble deploying a replica DC in my AD infrastructure. Currently we only have one DC and I'd like to have some sort of redundancy in the event it goes down.
We have an Windows Server 2003 R2 DC with AD installed. We extended the schema for Exchange 2010.
I'd like to run dcpromo and replicate the AD infrastructure to the new Replica DC, but I keep getting an error telling me the versions are incompatible. What are the steps I need to take to properly replicate the AD information to the new DC? Is it is a simple as running adprep? If so what version (from the exchange disc or the Windows server 2003 R2 disc?).
Thanks in advance for any information you can provide.
