Domain join fails due to missing signing

[andikrueger]

I did deploy a new Windows 10 VM using the DSC extension in Azure. The first run during the ARM deployment failed. I tried to run the existing config from PowerShell and see the following signing error:

VERBOSE: [w10]:                            [] Consistency check completed.
