Here is a webpage devoted to deploying Microsoft Windows Vista.
It contains a Step by Step guide to the deployment tools and the webpage talks about the new tools and technologies. It doesn’t cover off using Windows Deployment Services however. Information on WDS can be found here. Also to note that through the Vista certification webcast on Wednesday, I learned Microsoft is planning on releasing a Vista Deployment certification exam (70-624).
Myself, I am using Virtual Server R2 SP1 Beta 2 to get some experience using the deployment tools. I haven’t installed Longhorn yet to play with WDS, but I do have a copy I received at EnergizeIT to try out.
