Welcome to Part 2 of this article series. In Part 1, we started off by discussing the goal of this lab. That goal is how to deploy a single Enterprise Edition OCS 2007 R2 Server which is connected to an x64 SQL Server 2008 Back-End Server. We first discussed what the lab setup is going to be using Hyper-V, and then proceeded to the configuration of our Enterprise Certificate Authority.
