Windows Server uses a tool known as Failover Cluster Manager to create highly-available services. These range from file-shares all the way through to multi-tenant MSSQL Clusters. Failover Cluster Manager makes the management of the components for these services easy and provides great visibility of your services.
Which of my hosts are active?
- To check which node in your cluster is currently active, please follow the below steps. (This guide assumes that you have already logged in to your cluster using the cluster ip)
Select start, then select “Failover Cluster Manager” from the list of available programs as below
You will now be presented with the Failover Cluster Manager as below, from this pane, you are able to view information on your cluster, and carry out any administrative tasks. From the left hand pane, please select the cluster (This will be the name which you have configured for your cluster, in this example it is name “contosofile.contoso.domain”).

You will now be able to see 5 menu items below the cluster name which you have expanded, please select the “Roles” option from the menu. The central pane will now display information on all of the available nodes within your cluster, each service will display, status, type, and owner node as below.
