In one of my environments, running a 5 node cluster, I have a single node in this cluster that despite having successfully installed and updated the version of the server components is still showing in the SQL Backup UI as needing an update.
The imagine below confirms that all of the instances hosted on the problem node have the same version of the server components :
This image then shows what the SQL Backup UI is showing. The icon indicating that there is a newer version of the server components is showing and looking at the properties for this node, it shows that the SQL Backup version is still the old version :
Is there somewhere in the file system/registry that I can look at/update to force the SQL Backup UI to see this node as actually being up to date ?
