Are you curious about DirectAccess, the new feature in Windows 7 and Windows Server 2008 R2 that provides transparent and automatic intranet access when roaming on the Internet? Answer: Yes, what a silly question!
Do you want to see it working for yourself? Answer: Yes, right now as a matter of fact!
Check out the Step By Step Guide: Demonstrate DirectAccess in a Test Lab, a new white paper that guides you through setting up 6 computers running the Release Candidate versions of Windows 7 or Windows Server 2008 R2 and demonstrating DirectAccess functionality when on a simulated Internet with a public IPv4 address, a private IPv4 address (behind a NAT), and when behind a simulated corporate firewall/proxy server.
You can use physical computers or a VM setup.
Download, configure, be amazed, and, most of all, enjoy!
