will be imaged must be physically connected to the network. They can be computers with existing

operating systems of any kind, or they can be new computers with no operating system installed.

Limitations

One significant limitation of using multicast without installing any ZfD software is that it results

in a set of computers that have duplicate network identities—the IP addresses, Computer

(NETBIOS) names, Workgroup memberships, and Security Identifiers (Windows NT/2000 only)

are all the same and will cause conflicts if deployed on the network without change.

For a handful of computers, this might not be a problem. But for a larger number, if the computers

have Windows*, we recommend that you install the ZfD imaging agent on them before doing the

multicast. (You can use an Application object to do this easily. See Installing the Imaging Agent

to Safeguard Workstation Identity Data in Setting Up Workstations for Imaging in Workstation

Imaging in Deployment.) The imaging agent saves the computer’s network identity settings before

the multicast session and restores them afterwards.

Multicast Procedure

There are a couple of ways to conduct a multicast session. You can:

 Define an automatic session and the participating computers in ConsoleOne

 Physically visit each computer yourself and start the multicast sessions one at a time

Defining an Automatic Session

1 (Optional) Install the ZfD imaging agent on each of the participating computers.

See “Why Use Multicast?” on page 215 for the reasons and for further instructions.

2 In ConsoleOne, right-click the Server object > click Properties > the ZENworks Imaging tab.

3 Click Add > type a name for the multicast session > click OK.

4 On the Multicast Session Settings page, specify the Master Image Source.

You can specify an image file or a master workstation.

A workstation cannot be the master if it is being used as a master in another multicast session

or if it explicitly participates in any other session.

5 Decide how many participating workstations you want to have booted up before the multicast

session begins. Specify this number in the Clients Have Joined text box.

The default if you do not specify a number is 5 workstations.

6 If not enough workstations have booted up to fulfill the Clients Have Joined requirement, the

multicast session will begin if a participating workstation boots up and certain amount of time

passes without another participating workstation booting up. Specify this amount of time in

the Minutes Have Elapsed Since a New Client Has Joined text box.

The default if you do not specify a time is 15 minutes.

7 To delete the session after it has finished, select the last check box.

8 On the Multicast Session Participation page, click Add under Include the Following

Workstations to explicitly add the workstation objects that you want to include in this

multicast session.
