Description: Removes a multicast transmission. Unless you specify /Force,
             existing clients will complete the image transfer but new
             clients will not be allowed to join.

Syntax:
WDSUTIL [Options]
        /Remove-MulticastTransmission
        /Image:
        [/Server:]
        [/Force]
        /ImageType:{Boot | Install}

/Image:
        The name of the image that is associated with the
        transmission.

[/Server:]
        The name of the WDS server. This can be either the NetBIOS
        name or the FQDN.  If not specified, the local server will be
        used.

[/Force]
        Stops the transfer of all clients and deletes the
        transmission.

/ImageType:{Boot | Install}
        The type of image that is associated with the transmission.

For boot image transmissions:
-----------------------------
WDSUTIL [Options]
        /Remove-MulticastTransmission
        /Image:
        [/Server:]
        /ImageType:Boot
        /Architecture:{x86 | ia64 | x64 | arm}
        [/Filename:]

/Architecture:{x86 | ia64 | x64 | arm}
        The architecture of the boot image that is associated with the
        transmission to start. Since it is possible to have the same
        image name for boot images in different architectures, you
        should specify the architecture to ensure that the correct
        transmission is used.

[/Filename:]
        If the source image cannot be uniquely identified by name, you
        must specify the file name.
