Windows 2008 non-R2 Windows Backup Fails: Event ID 517

Symptoms: 
Windows Backup Fails and you receive the following Event ID
      EventID:  517
      Source:  Backup
      Description: 
EV_RenderedValue_0.00

The resource loader failed to find MUI file

 Solution:
This is a common issue and the way I was able to resolve it is to resize the C partition.  For some reason VSS can't read the last part of the C partition and will fail at 99%  (You can verify this by trying to run backup in a command line)


Just go to Disk Manager and resize and shrink the C partition by some small amount.  10MB or something.  Then try to run the backup again.
