I'm trying to rename my cluster via the GUI. Its not in production so I decided to see if it would 'just work' and it doesn't. I've rebooted both cluster nodes and still this happens when I try to rename it.
I'm still able to connect to the cluster and view the various elements being online via the GUI, except under Cluster Core Resources, it shows the server name with the status of "Failed".
I've reviewed DNS and AD to see if the new name I entered via the GUI went through but my management console is not reporting it, but this is not the case, I can't find any trace of the name change aside from the failure of the change and the failed status of the Cluster Core Resource.
The most pertinent Cluster Event I can see is Event ID 1069:
"Cluster resource 'Cluster Name' of type 'Network Name' in clustered role 'Cluster Group' failed."
