New User PC, Backup Failing, The Windows Server Client Backup Computer Service is not present
Question
-
I replaced a PC on the user's SBS 2011 Essentials site
After connecting the new PC to the network with the wizard everything appeared successful but that night and ever since, the new PCs backup failed.
Manually rerunning the backup it failed again
In the error log I saw that VSS was getting 8194 errors "Volume Shadow Copy Service error: Unexpected error querying for the VSSWRITECALLBACK interface. hr=0x80070005, access is denied...". Ran VSSADMIN LIST WRITERS but there were NO errors listed.
User PC backup works on the other PCs on this site, and worked for this user's previous PC so it is unlikely that the problem is in the server. All other user activity seems to be working (drive mappings, etc) the wizard seemed to run without error and seems to have done the connection correctly otherwise. Nothing special about the user - same software she has been running on her old pc, windows 7, just faster PC hardware (Lenovo Tiny).
After a bit of research into fixing that stumbled on the fact that the "Windows Server Client Computer Backup service" on the new computer was absent. Presumably it is required for the client backup to work.?
How to remedy ?

I don't see the Windows Server Essentials Client Computer Management Service on the client.
I see "Windows Server Client Computer Backup Provider" and it is running.
Still, the backup fails as described above.

Hi,
As your screenshot has been displayed, for SBS 2011 connecting client, Windows Server Client Computer Backup Provider Service is responsible for client backup:
For the client computer backup problem, please try below suggestion:
1. On client, open CMD and type “chkdks /r /f” to check/repair disks.
2. On SBS server, please manually disable, and re-enable backup on specific client to check the result.
3. If problem persists, please reference above steps to dis-connect client and re-connect it to SBS to check the result.
Best Regards,
Eve Wang

1. It looks like may need to disconnect and reconnect.
In the link
"How do I disconnect or reconnect my computer from and to the server:
https://technet.microsoft.com/en-us/library/disconnect-reconnect-computer-network-1(v=ws.11).aspxin step 2 "Ensure the computer is removed from Window sSBS 2011 Essentials" The Link in that page does not go to the right page. Presumably I just remove the computer on the dashboard, and then on the PC change the network to workgroup?
2. Looking at the error report it certainly looks like a problem on the PC ? The backup is scheduled at 7:15
And at 8PM there was a group of VSS errors on the pc alike this:
Message: 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.
Operation:
Gathering Writer Data
Context:
Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220}
Writer Name: System Writer
Writer Instance ID: {4d4c9cfa-3b4b-4d07-99f2-0da740d7099c}Could this be a VSS issue?
