We have windows 2019 file server clusters that get "Cluster network name resource failed to register DNS name" errors"
We have performed the below actions by simply removing the troubled DNS record(s) then failing over and forcing a dns registration; however this error seems to continue to return. Do you have any recommendations as to the root cause of this?
Could you please confirm if the cluster members has permissions on the DNS record of cluster object?
Refer to the section - Creating DNS entries for the CNO
