Introducing a new 2008 Server to an existing 2003 single domain.

I am looking to add a new Windows 2008R2 server, which will eventually replace one of my existing (Windows 2003) domain controllers. Currently, I have two existing Windows 2003 domain controllers in my single domain environment.

I have done some research, but I am seeking clarification regarding the process of introducing a new 2008R2 server to an existing single domain forest with existing 2003 domain controllers. More specifically, the order of the steps surrounding domain and forest prep commands.

Any input is greatly appreciated.

Run on your DC in command-line

Dcdiag /v

To check domain health. If there are no errors, run

Netdom query fsmo

Locate schema owner and infrastructure owner.
Log on to schema DC and run

Adprep32 /forestprep /rodcprep

On infrastructure DC run

Adprep32 /domainprep /gpprep

Promote your 2008 server running

Dcpromo

Set up it as DNS and Global Catalog

After that you can consider transfering FSMO role to it and DHCP database migration.

Regards,
Krzysztof

You need to use /rodcprep if you want to use rodc dc in your network. If not, skip it but remember that before deploying the first rodc you have to run

Adprep /rodc
