If you try to run any of the CmdLets in the WDS PowerShell cmdlets remotely via Invoke-Command, Enter-PSSession, CIMSession, or even PSEXEC it will fail with the error:
_The operation being requested was not performed because the user has not been authenticated.
If this is happening to you, you are screwed. Kind of. Remotely managing an AD Integrated WDS is simply impossible as far as I can tell. To fix this is you have to remove the WDS role and then add it again. When you configure the server the second time around be sure to select “Standalone server”. Happy remoting.
