Install 64-bit Microsoft Windows Server 2008 with the Windows 6.0-KB950050-x86.msu patch on Master and Replica, each with a CPU and motherboard capable of running Hyper-V. The Replica does not require Windows Server 2008, 64-bit.
Configure the same number and type of network connections on the Replica that exists on the Master.
Both Master and Replica servers should reside in the same Active Directory forest and be members of the same domain or trusted domains.
