The networking model changed significantly in Windows Server 2008 Failover Clustering. First, and foremost, when we start talking about networking in 2008 Failover Clusters we need to drop some of the older concepts that have been around for awhile. Probably the one that needs to go first is the concept of 'Private' network. This term no longer applies in W2K8. All networks detected by the cluster service, and hence the cluster network driver, are, by default, classified as 'mixed' networks and are automatically configured for use by the cluster.
