Windows Server 2008 Simulator: Link

A true Windows Server 2008 simulator is not merely a video or a click-through demo. At its best, it is a lightweight, virtualized instance (often running on VirtualBox, VMware, or a browser-based sandbox) that mimics the file system, the graphical user interface (GUI), the registry, and critical server roles such as Active Directory Domain Services (AD DS), DNS, DHCP, and IIS. Unlike a production server, a simulator allows the user to make catastrophic errors—deleting the NTDS.dit file (the Active Directory database), misconfiguring group policies, or crashing the DNS resolver—without any real-world consequence. This "permission to fail" is the simulator’s greatest pedagogical asset.
