hi there, question, what are the differences between a domain with w2008 or with w2008 r2 domain controllers / forrest- and domain-level? we're about to plan to deploy a windows PKI but we dont know what function mode we should choose and what if we should upgrade the DCs to 2008 r2 and if we had important features we're missing if we're using the "old" version. thanks for responses, uerueluem
