If you're doing any kind of virtualization work with Hyper-V Server 2008, then you might be interested in downloading the Hyper-V Server 2008 Setup and Configuration Tool Guide

The guide has all the information you need to setup and configure Hyper-V Server 2008.  It covers everything from setting up local administrator passwords, to details about the new Hyper-V configuration tool as well as remote management using Windows Vista SP1 (with Hyper-V Manager MMC), Windows Server 2008 or System Center Virtual Machine Manager.

While you're at it you might also want to grab the Hyper-V Planning and Deployment Guide which has details about hardware requirements and limits, supported guest operating systems, and instructions for installing the role and management tools.

Happy Virtualizing!!!
