Bad Hyper-V username logon attempt - Cluster Computer Account

Hi all,

We have VeeamONE monitoring our servers for issues, and we get this one appearing once or twice a month, usually a day or two after the Windows Update patch maintenance window. 

We have two Clusters, though this message is only appearing for one of these clusters. It does happen to both members in the cluster, though.

4625 Microsoft-Windows-Security-Auditing
Event description: An account failed to log on.

Failure Reason: Unknown user name or bad password.

Account Name: Cluster2$

Account Domain: domain.local

The cluster seems to be running OK, so I'm not sure if this is a problem that I need to be concerned about.

Though the Red errors in our monitoring dashboards really annoys our CEO/CIO.

I seem to recall that account being created automatically during the Failover Cluster set-up (around four years ago), and that the password was auto-generated.

Should I be updating the password? If so, can I do it without breaking the cluster?
