Creates a new multicast transmission for an image. This command is equivalent to creating a transmission using the MMC snap-in (right-click the Multicast Transmissions node, and click Create Multicast Transmission). You should use this command when you have both Deployment Server and Transport Server role services installed (which is the default installation). If you have only Transport Server installed, use /new-Namespace.

Parameters

Parameter Description

/Image:<Image name>

The name of the image to be transmitted using multicasting.

[/Server:<Server name>]

Specifies the name of the server. This can be either the NetBIOS name or the fully qualified domain name (FQDN). If no server name is specified, the local server will be used.

/FriendlyName:<Friendly name>

Specifies the friendly name of the transmission.

[/Description:<Description>]

Specifies the description of the transmission.

/ImageType:Install

Specifies the type of image to be transmitted using multicasting. Note that this parameter must be set to Install.

[/ImageGroup:<Image group name>]

Specifies the image group that contains the image. If no image group name is specified and only one image group exists on the server, that image group will be used. If more than one image group exists on the server, you must use this option to specify the image group name.

[/Filename:<File name>]

If the source image cannot be uniquely identified by name, you must use this option to specify the file name.

/TransmissionType:{AutoCast | ScheduledCast}

Specifies the type of transmission to create.

  • Auto-Cast. This type indicates that as soon as an applicable client requests an install image, a multicast transmission of the selected image begins. Then, as other clients request the same image, they too are joined to the transmission that is already started.

  • Scheduled-Cast. This type sets the start criteria for the transmission based on the number of clients that are requesting an image and/or a specific day and time. If you do not select either of these check boxes, the transmission will not start until you manually start it..

For Scheduled-Cast transmissions, you can also specify the following options:

  • [/Time: <time>] - Sets the time that the transmission should start using the following format: YYYY/MM/DD:hh:mm.

  • [/Clients: <Number of clients>] - Sets the minimum number of clients to wait for before the transmission will start.

Examples

To create an Auto-Cast transmission, type:

WDSUTIL /New-MulticastTransmission /FriendlyName:"WDS AutoCast Transmission" /Image:"Vista with Office" /ImageType:Install /TransmissionType:AutoCast

To create a Scheduled-Cast transmission, type:

WDSUTIL /New-MulticastTransmission /FriendlyName:"WDS SchedCast Transmission" /Server:MyWDSServer /Image:"Vista with Office" /ImageType:Install 
/TransmissionType:ScheduledCast /Time:"2006/11/20:17:00" /Clients:100
