I agree that it took us long enough to get this thing posted since I first mentioned it back in February.
This kit includes everything you need to test drive a Server and Domain Isolation deployment on Windows Server 2003 and Windows XP.
Did I say WS03 and XP?
Yes. But, don't fret.
We're working with Ron to get an updated version of the demo that highlights all the great stuff we've done in Windows Vista and Windows Server 2008. This version (no pressure Ron!) should hit the streets around the RTM/Launch of WS08. Stay tuned!
Okay, back to describing the one you now have at your disposal: You'll find 5 pre-configured VHDs and some great documentation that will step you through both basic and advanced S&DI scenarios. Ron's done a great job with visualizations that help tell the story and explain the data flows, etc. when trying out the different scenarios (like the "Start Page" shown below).
After you've been wowed by the great stuff you can do with S&DI (which is an out of the box security solution with WS03, XP and Win2K, and WS08 and WinVista), visit our TechNet Server and Domain Isolation site at http://www.microsoft.com/sdisolation to learn more, review customer case studies, and download deployment guidance.
