Message Text

Failed to open the Windows Server Failover Clustering registry subkey '%.*ls' (Error code %d). The parent key is the cluster root key. The WSFC service may not be running or may not be accessible in its current state, or the specified arguments are invalid. If the corresponding availability group has been dropped, this error is expected. For information about this error code, see "System Error Codes" in the Windows Development documentation.

If a WSFC cluster is destroyed, it removes all registry keys related to AlwaysOn Availability Groups.

After re-creating a WSFC cluster, disable and then re-enable AlwaysOn on every cluster node on which an instance of SQL Server is enabled for AlwaysOn. You can use the SQL Server Configuration Manager for this task.
