VSS Error in performing backup to Windows server

A new Workstation was recently added to our Domain and won’t complete client backups.  It is the first Windows 10 workstation and this might be an issue as all the rest are Windows 7.  Backup Tab on the Computer Properties in the Lists all the backups as “Unsuccessful”.  All the other workstations are performing properly.

The Backup details show:

Local Disk (Unsuccessful 1GB) 

Local Disk (Unsuccessful 236.7GB)

An error prevented backup from running

An error prevented backup from creating snapshot of the volumes on this computer.

For more information about this issue, see the event logs on the computer that you are backing up.

For information about how to resolve issues with backup see the Troubleshooting section in the online Help.

I checked the local logs on the workstation and under the Application log at the times of the backup I would see:

General Tab:

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface.  hr = 0x80070005, Access is denied.

. This is often caused by incorrect security settings in either the writer or requestor process.

Probably, there is no sufficient rights to perform backup.

Please, follow the next thread and read the answer by milo_one.

Hi,

Based on your description, I suggest you:

1、Uninstall third party backup software and antivirus software if any.

2、Make sure Volume Shadow Copy service is running: if it’s stopped, make it start and set up its Startup type to Automatic.

3、Start dcomcnfg.exe, right-click on My Computer, select Properties, then grant NETWORK SERVICE Local Access to all COM components as shown:

Hope these could be helpful.
