It monitors the network interface card (NIC) in the node. 
To attach an IP address, A NIC resource should be online first and is needed to be monitored. 
In a system with several NICs are installed, each NIC resources of MCCS must be able to identify those under its management. To identify those, you can use the name registered in the MAC address or device driver, or the name registered in the network connection registration information. The NIC resource of MCCS uses uses the name (FriendlyName) registered in the network connection registration information. 
This name is shown in the 'Network Connection' screen, or the information displayed after 'Ethernet Adapter' when you run the 'ipconfig' command in the command prompt is the name used to identify a NIC. 
The NIC resource defines this name by using the AdapterName attribute.

Fault

A NIC is not configured or a link is disconnected. 
So, all the ICMP tests to the testing address failed.

OnlineA NIC resource cannot be brought online.

*Network card resource characteristics

MCCS cannot use the online/offline commands to a network interface card. It is because a NIC is managed as MonitoringOnly resource.
Due to the characteristics, an Action attribute of its resource type is set to None. Also, its NoAction value of resource attribute is set to true. 
When a resource's attribute set to like these, this cannot be brought online or taken offline. It is online at all nodes at the same time and is only monitored the state.
