In the last day or so I've discovered that I'm no longer able to connect to my cluster using Failover Cluster Manager. When I try to connect it gives me the error "An error occurred connecting to the cluster <cluster name>. An error
occurred trying to display the cluster information. One or more errors occurred."
If I log onto the node that's hosting the "Cluster Group" cluster resource, and open Failover Cluster Manager and connect to <Cluster on this server...> it gives me a similar message.
As far as I can see, the Cluster Powershell commands still work, so I've moved the "Cluster Group" group to another node, but I am still unable to connect to the cluster using Failover Cluster Manager.
The Cluster Service is running, and I'm reluctant to restart it becuase I know my Virtual Machines are going to start failing or failing over when I do this.
I have verified that I am logged in as a super-duper user, even tried logging as the Domain Administrator with no luck. I have also tried the WMI Mofcomp suggestion as described in http://www.yusufozturk.info/windows-server/failover-cluster-manager-an-error-occurred-to-display-cluster-information.html with no luck.
Any suggestions?
