Some applications may be unable to access remote targets or resources on devices running Windows 10, version 1903, especially non-domain joined devices.
Applications that use Distributed Component Object Model (DCOM) and rely on credentials from the Credential Manager API (credman) for authentication to remote targets may experience authentication failures on Windows 10, version 1903.
