Microsoft® Exchange Server 2007 setup displays this warning because the current Microsoft Windows cluster environment has only one network interface that is defined.
It is a recommended best practice to implement at least one network interface for the public network (client connection) and one network interface for the private network (administrative/heartbeat) to avoid a single point of failure.
To address this warning, implement at least one additional network interface for the Microsoft Windows cluster.
For more information about the optimal network configuration for Windows server clusters, see "Server Clusters: Network Configuration Best Practices for Windows 2000 and Windows Server 2003" (http://go.microsoft.com/fwlink/?linkid=34304).
