As a moss administrator I am often confronted with questions that need some research and testing. For this I am always using a virtual MOSS environment. I recently stumbled upon a post that explains all the steps for creating a complete MOSS 2007 VPC image. I know it is still a Virtual PC image and not a VMWare image, but hey, you VMWare guys have VMWare Converter for that, right [8-|].
So go have a look at the complete post for setting up your MOSS 2007 VPC Image.
