PSAlert_4604_NTSERVICE_SERVICE_MONITOR_ERR_Monitor (UnitMonitor)

Knowledge Base article:

Summary

The monitor probe failed on the specified server. The server may no longer be suitable for the virtual host associated with the monitor. If the virtual host was active on the affected server, it may have failed over to another server. (Whether failover occurs is dependent on the configuration of the monitor and the virtual host.) Verify that the monitor is configured correctly. Check the server and the network interface associated with the virtual host for problems.
