You can configure Windows Server 2008 R2 to authenticate users connecting to a wireless network using WPA-EAP or WPA2-EAP (also known as WPA-Enterprise or WPA2-Enterprise) authentication. This video, created for the second edition of the Microsoft Press 70-642 Training Kit, shows you exactly how to do that.

A new version of Internet Explorer is almost ready–IE9. You can download the IE 9 Release Candidate (RC) for free. The RC is “feature complete”, which means they might change things, and they’ll definitely fix some bugs, but they won’t be adding or removing any features.

Here’s a video overview I recorded showing the various improvements and comparing it to my current favorite browser, Google Chrome.

A question from a reader:

Hello,
I hate to bother you but I have been reading on the internet about the multi-screen topics you write about. If you have time to answer my question – I would greatly appreciate it.
I have been assigned what seems to be an impossible project – and given almost nothing as a budget.
My company want me to create a 3 TV set visual in our business.
I see where you write about similar set-ups – I had hoped you can give me some direction.
This is ULTIMATELY what I would like to make happen.
We have a computer that sits there and has little other purpose.
I would like to use this computer to drive 3 modern TV sets (which have perhaps VGA inputs). I see some links you provide to companies that make video splitting devices – but we would need the model that costs almost 2 thousand – which is my entire budget – so this won’t work. Anyway – I am looking for a cheap way to connect 3 TV sets to a computer AND have the computer to run 3 separate programs which will feed these 3 separate TV sets. I may be able to get this down to 2 TV’s – but 3 is the ultimate goal.
What have you seen or read about that is cheap that may be able to do what I need? I really would appreciate any advice you have on the subject.

And my answer:
