Details of the scenario you tried and the problem that is occurring
Use OfficeOnlineServerInstall pointing to a non-NTFS filesystem such as a mounted ISO image. The routine tries to check for the zone.identifier alternate NTFS data stream, fails, and throws an error which causes the DSC routine to report that it was unsuccessful and installation does not proceed.
