SMB Witness Service Protocol Security Callback Failure

Microsoft.Windows.FileServices.Service.SMB.10.0.WitnessAccessDenied (Rule)

Knowledge Base article:

Summary

SMB Witness Service failed a request from another computer due to the computer not having the proper security level.

Causes

This can occur if an attempt to register for SMB witness registration from a computer that is not joined to a domain in the same forest as the SMB Witness service or if an administrative command is run from a computer outside the file server cluster.

Resolutions

Make the sure the computers accessing file shares in the file server cluster are joined to a domain in the same forest as the file server cluster and make sure to run administrative commands on one of the cluster nodes.
