I love the new version of IIS. One of the great elements of Server 2008 is that it has IIS7 installed. A great aspect of the new IIS is that you can now run very common applications (wordpress, and photo gallery) on Windows. These applications are PHP based and typically are hosted on Linux Servers. IIS 7 allows for you to host these applications on Windows with some great performance
A new tool from Microsoft allows you to install all of these applications with little or no configuration.
(Web Application Installer) http://www.microsoft.com/web/channel/products/WebApplicationInstaller.aspx
Applications: DotNetNuke, Drupal, Gallery, Graffiti CMS, osCommerce, phpBB, WordPress
Give it a try. Works on Vista sp1 and Server 2008
