When I try to run a windows backup, it fails immediately when it tries to create the snapshot... in event viewer it says this:
Volume Shadow Copy Service error: Unexpected error calling routine UnregisterDeviceInterfaceNotification(00000000003F32B0) [1062]. hr = 0x80070426, The service has not been started.
.
I have already gone through and changed the shadow copies for the tiny boot partition to use the C drive instead (this fix has worked on several other servers, but this server persists with this confounded mysterious error).
I can manually start and stop the Volume Shadow Copy service - it's set to manual and has no problem starting or stopping. What other service could this error be eluding too?
Here is a list of my vssadmin list writers:

I do not know enough about VSS and all these writers to do any good... I found a script to run from another forum which starts and stops some services, and it seems to change my writers list... the bat file does this:
net stop EventSystem
net stop swprv
net stop vss
net stop winmgmt
net stop apphostsvc
net start apphostsvc
net start EventSystem
net start swprv
net start vss
net start winmgmt
When the batch file completes, then my vssadmin list writers looks like:

Running a backup when "No error" is listed still fails...
This is a 2008 R2 domain controller... Anyone have any ideas?
