Cluster network name resource failed registration of one or more associated DNS name(s) for the following reason: DNS bad key. Event ID 1196

Hello,

We have a server 2016 failover cluster with 1 clustered role on it.  In the event log of the cluster we are getting the following:

"Cluster network name resource "SQL Network Name (SQLSRVIT)" failed registration of one or more associated DNS name(s) for the following reason: DNS bad key."

I have checked the DNS server settings in the NIC and they are pointing to a valid working DNS server.  

This error happens every 15 minutes.  

What else can I check to try to fix this?

Thanks

James
