TechNet Virtual Labs
Ever wanted to test Microsoft's newest software in a totally secure sandbox environment? Wouldn't it be great to be able to test new servers immediately, without formatting hard drives or dedicating one or more computers to the project? Now you can, with the TechNet Virtual Labs.

The Virtual Labs are available via this link

There's a huge range of labs available for you to play with and learn how techniques such as network isolation / segmentation can be applied via IPSec all for free via your browser. Each lab is designed to take up to 90 minutes.

I've picked the broad topics that I think you'll find most useful from a security perspective and listed them below. There are many other areas including SQL and Exchange.

It's easy to gain access to the labs - you need to register - this is NOT some kind of sales ploy - your privacy is respected and hence you won't receive follow up emails unless you opt for them. The only catch is that the registration for forces you to select a "State" which is pretty meaningless unless you're a resident of the USA - I picked "British Columbia" being a UK citizen as at least half of the name is right & BC's a really nice place!
