Resource in the Fail Over Cluster is a part of the "Application HostingModel". |

Resource in the Fail Over Cluster is a part of the "Application Hosting
Model". An application is modeled as a set of resources in a group that has
dependency on other resources. NLB is completely application unaware, and
does not have any "Application Hosting Model". If your application crashes
NLB has no clue. For example if your application is IIS and it has crashed
on one of the nodes NLB cannot care less and keeps accepting traffic to that
node.
You can compensate this either by providing your own monitoring system, and
then adjusting port rules on the cluster nodes, or by utilizing System
Center Operations Manager
