If you're interested to chat with, and pose questions to, the Active Directory team, then plan to join a Web chat on Wednesday, Feb. 22 at 10am Pacific time. It's available off of TechNet/community site. Here's the abstract for the 60-minute chat:
Please join leading Windows Server product and program managers to discuss the future of Active Directory and its evolution from a NOS directory service to the core identity and access infrastructure for organizations of all sizes. Discover what's new in Active Directory in Longhorn Server and what's planned for future releases.
This subject is timely because just today the group announced "vision and roadmap" for Active Directory.
