Add-ClusterNode Error: Keyset Does Not Exist

Jonathan Kehayias troubleshoots a Windows Server clustering problem:

While working on a video recording for Paul this week I ran into an interesting problem with one of my Windows Server 2016 clusters. While attempting to add a new node to the cluster I ran into an exception calling Add-ClusterNode:

The server ‘’ could not be added to the cluster.
An error occurred while adding node ‘’ to cluster ‘SQL2K16-WSFC’.

Keyset does not exist

The windows account I was using was the domain administrator account and I had just recently made modifications that involved the certificate store on this specific VM, so I decided to take a backup of the VMDK and then revert to a snapshot to try again, and this time it worked.  So needless to say I was intrigued as to what I could have done that would be causing this error to happen.

Read on to see what the root cause was and how you can fix it.
