Summary

DHCP Cluster Server 2012 R2 Server Discovery get the DHCP Cluster 2012 R2 Server object, related properties and relationship.

These are the parameters that we could override, if need it:

Interval Seconds: Amount of Seconds for each execution
Sync Time: Time expressed with this format: "hh:mm" since you will like to start the execution.
Timeout Seconds: Amount of seconds to wait until cancel execution for "timeout reasons."

Element properties:

Target	Microsoft.Windows.Cluster.VirtualServer
Enabled	True
Frequency	86400
Remotable	False
