Hi, I'm receiving this error for writing processes "Dhcp Jet Writer" and "System Writer".
My server is a WS2012
I went to HKey_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\ProfileList to check if i could find a *.bak entity but there's not:

From an elevated prompt I launched "vssadmin list writers" and I got a list without errors:

Do you have any suggestions?

    Hi,
    Have you checked the event log if it recorded the error 0x80070005?
    https://support.microsoft.com/en-us/help/2991246/access-is-denied-error-when-you-perform-a-backup-or-run-vssadmin-list
    Error code 8194 is an "Accessed Denied" error caused by the inability of one or more VSS system writers to communicate with the Remote Backup VSS requestor process via the "COM" calls exposed in the IVssWriterCallback interface. Try to add service account permission to COM.

    Locate the writer on the list, and restart the correlating service, then rerun vssadmin list writers to ensure the writer is stable.
    Follow the below steps to resolve the issue:
    go to comman promt and go to system32:

    cd /d %windir%\system32

    COPY THIS COMMAND AND PASTE IT
    net stop vss
    net stop swprv
    regsvr32 ole32.dll
    regsvr32 oleaut32.dll
    regsvr32 /i eventcls.dll
    regsvr32 vss_ps.dll
    vssvc /register
    regsvr32 /i swprv.dll
    regsvr32 es.dll
    regsvr32 stdprov.dll
    regsvr32 vssui.dll
    regsvr32 msxml.dll
    regsvr32 msxml3.dll
    regsvr32 msxml4.dll
    It will re-register all the the dll's.
    Restart the VSS service.
    Hope this helps and please help to accept as Answer if the response is useful.
    Best Regards,
    Carl
