I was looking for upgrading my machine to new operating system and one the option was Windows Server 2008. Some of deployment features, like WAS are supported here.
I found that Microsoft offers a certification program and more information can be found here.
An application based on the features its offer and the market it targets can participate in one of these programs meet the technical bars for the Certified for Windows Server 2008 logo or the Works with Windows Server 2008
Microsoft is providing additional tools this time in addition to the test case document. I am going to download the tools and let me write of them later.
