[/Threshold:]   For /Policy:AutoDisconnect, this option
                                      sets the minimum transfer rate in KBps.
                                      Clients that drop below this rate will
                                      be disconnected from multicast
                                      transmissions
   [/StreamCount:{2 | 3}]             For /Policy:Multistream, this option
                                      determines the number of sessions.
                                      2 means two sessions (fast and slow)
                                      3 means three sessions (slow, medium,
                                      fast).
   [/Fallback:{Yes | No}]             Determines whether clients that are
                                      disconnected will continue the transfer
                                      using another method (if supported by the
                                      client). If you are using the WDS client,
                                      the computer will fallback to unicasting.
                                      Wdsmcast.exe does not support a fallback
                                      mechanism. This option also applies to
                                      clients that do not support Multistream.
                                      In that case, the computer will fall back
                                      to another method instead of moving to
                                      a slower transfer session.
