Prepare your SBS domain for an additional R2 Domain Controller

I came across this article the other day and found it an interesting read. It's called, "How to prepare the SBS domain for an additional R2 Domain Controller". It walks you through how to upgrade the Active Directory Schema on an SBS server to R2 if you purchase a new member server preloaded. Basically it uses the disk from the Server 2003 R2 set and runs the adprep tool from within it. After that you can insert additional domain controllers that are Server 2003 R2 into any SBS network.
