Network Interface State Monitor

Microsoft.Windows.2003.Cluster.NetworkInterface.StateMonitoring (UnitMonitor)

Implements monitor for network interface.

Knowledge Base article:

Summary

This monitor checks the status of a cluster network interface. If the state is 'Network Interface up', the network interface can communicate with all other network interfaces whose state is not 'Network Interface down' or ‘Network Interface unreachable’. If the state is 'Network Interface unreachable', the network interface cannot communicate with at least one other network interface whose state is not 'Network Interface down' or 'Network Interface unreachable'.

Causes

An unhealthy state for this monitor indicates a problem with the network adapter. View all current alerts from this network adapter using this link:
