I know that many of you have been asking for Information Technology (IT) related demos. So first off, let me point you toward one of our sister sites: TechNet Edge. It is constantly being updated with really great deep dives, demos, and other IT related information. I know it can be daunting sometimes... so I had another chat with Stefan, the Mega-Microsoftie.
He dives int TechNet Virtual labs, a freely available tool that allows you to dynamically provision virtual server instances that you can interact with all within your Internet browser. Why is this cool?? Well you guys want the latest technology? Check. Want to run 6 simultaneous servers including a Domain Controller, Active Directory, Windows Server 2008? Done. Oh and did I mention... again... it's FREE.
Do a search on live.com for "TechNet Virtual Labs" and it will be one of the first results (I would link you but my result is the English-US version).
PS: stay tuned after the closing for a look at a fun piece of hardware Stefan has on his desk... cool eh?
