So I spent some time yesterday trying to find this article about How to Configure Windows Server 2008 for Site Systems, and unfortunately, in my google and live searches, I wasn't successful. . . I did find other posts from the deployment guys, technet social, and a couple other places, but none (that I noticed) referenced the official doc.
So hopefully this post will help you find the official doc for How to Configure Windows Server 2008 for Site Systems for ConfigMgr (System Center Configuration Manager 2007) in the future - I know it will help me :)
