Hi
We've started receiving the following error after a month or so of clustering bliss...
"Cluster network name resource 'Cluster Name' failed registration of one or more associated DNS name(s) for the following reason:
DNS bad key"(Event ID 1196).
....on one of the node in our two node 2012 Hyper-v cluster. The error is being produced on the node with Quorum and as such the node with the Cluster IP address. Also we're receiving a "The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server NODE-2$. The target name used was <PROTOCOL>/CLUSTER-NAME.contoso.local "(Event ID 4).
This is currently stopping us from Live migrating servers from the Quorum node to the other. From what I can tell its a kerberos authentication failure with the SPN CLUSTER-NAME and the Machine Account of NODE-2.
Configuration
2 x Windows Server 2012 Std Hyper-v Cluster
Shared storage
2 x LAG Teamed NIC on both server
If you require anymore info please let me know.
