If you are running Windows Server 2008 I hope by now you’ve picked up a copy of Windows Server 2008: What’s New/What’s Changed by Greg Shields. While this is a terrific resource to get you started, you’ll likely want some more in-depth information. Greg has a short lesson on migrating from FRS to DFS-R you might interest you at http://concentratedtech.com/content/index.php/tag/windows-server-2008/. I expect to see more Lunch Lessons in the future on Server 2008 and other topics as well.
