The deployment story in Windows Server 2008 (and Windows Vista, for that matter) has radically changed. Windows Deployment Services (WDS) replaces the old Remote Installation Services (RIS) product that was included with Windows 2000 and Windows Server 2003. It has a number of enhancements, improvements, and new features, but perhaps the most important and the most useful of them is the ability for WDS to read, manage, and stream the new Windows Imaging Format (WIM). WIM support was first baked into Windows Vista and solves a number of problems that you may have stumbled on if you've worked with imaging products for Windows in the past. While WDS can still deploy what it calls "legacy" images—for example, Windows XP installations in the format you used to use in conjunction with Remote Installation Services—WDS shines when you set up different WIM files with boot and install images for different architectures and systems.
With some upfront grunt work (and that may be putting it mildly), you can significantly reduce the time it takes to achieve a complete deployment on machines that are of different types, architectures, and configurations. Let's take a look at some critical components of the deployment infrastructure under Windows Server 2008.
