The OpsMgr Health service may incorrectly display the health state of the cluster nodes in System Center Operations Manager 2007

When you use Microsoft System Center Operations Manager 2007 to perform cluster node health monitoring, the OpsMgr Health service may incorrectly display the health state of the cluster nodes.

This problem occurs if the Windows Management Instrumentation (WMI) data source generates multiple events in a short time and if the events contain the same time stamp.

The ordering of the events that contain the same time stamp may cause the OpsMgr Health service to display the health state incorrectly. This behavior may affect cluster monitoring in System Center Operations Manager 2007.
