This article assumes you've already created the two guest OSs running Windows Server 2003 Enterprise Edition Service Pack 1 (SP1) or later, and they have a standard NIC connected to a public network.

You'll need at least two networks: the public network for regular communications to clients and a network for the private cluster node communication. Assuming the public network already exists, you'll create the private network by accessing the Virtual Server Master Status screen (https://virtualserver.domain.com:1025/VirtualServer/VSWebApp.exe?view=1 ) and click Create under the Virtual Networks left menu.

Enter a suitable network name and ensure None (Guests Only) is selected for the NIC to be used as the figure shows. Because this network is only for the guest OSs to communicate, it doesn't require physical network connectivity. Click OK.
