File Backup job failure possibly related to latest windows update

  • 18 January 2022


Hey all,

 A file backup job started failing when it attempted to run on Saturday the 15th. When the job ran on Friday evening, everything was fine, but it decided to start failing on Saturday. On Friday night, the recent Microsoft patch (kb5009557 2022-01 Cumulative Update for Windows Server 2019 (1809)) was installed after the Veeam job ran so I am thinking that the failure might be due to the update? Currently using Veeam Backup and Replication Build installed on a Windows Server 2019 Hyper-V machine. When looking in Event Viewer, I looked under the Applications and Services Logs tree and the failed job is given an Event ID of 190 with this message, “Job details: Error: Agent: Failed to process method {NasMaster.CreateIfNotExistsJobBackup}: You can't access this shared folder because your organization's security policies block unauthenticated guest access. These policies help protect your PC from unsafe or malicious devices on the network.” I have looked at the network and authentication settings of my NAS and everything there looks okay. Has anyone else experienced this after the latest Microsoft update?

On top of this you might want to upgrade to 11a with the latest patch via the ISO.  This might help address the issue also.
