File resource replacing files after changes are made

I’ve been playing around with custom lock screens for a bit and I can’t seem to get DSC to update the file each time I replace the backgroundDefault file in the C:\windows\system32\oobe\info\backgrounds directory. I had about a 80% success rate on deploying this to around 200 users.

Registry 'ScreenLock'
            Ensure    = ”Present”
            Key       = ”HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background”
            ValueName = 'OEMBackground'
            ValueType = ”DWord”
            ValueData = ”1”
        File 'Screens'
            SourcePath      = '\\x\x\backgroundDefault.jpg'
            DestinationPath = 'C:\Windows\System32\Oobe\info\backgrounds\backgroundDefault.jpg'
            Recurse         = $True
            Type            = 'File'
            MatchSource     = $True
            Ensure          = 'Present'
            Force           = $True

Have you scoured through the DSC logs on nodes that aren’t working, too see if you’re getting any useful information? It’s a little hard to debug just from the configuration script.
