Broadcast\Multicast Show

When this Policy is enabled you will have the ability to configure the Tutor Console to either perform a Broadcast or Multicast Show. When showing the Tutors screen to clients, the screen information is sent to each client machine in turn. Enabling Broadcast Show results in the screen information being sent to all machines simultaneously.

In some network environments where there is limited network bandwidth available or when showing to larger numbers of machines this will provide significant performance benefits.

If Broadcast Show is enabled please ensure that the correct Broadcast Address is applied using the Broadcast Address Policy.

If Multicast Show is enabled please ensure that a Mutlicast Address is applied by enabling the Multicast Address Policy.

Supported on: At least Windows 2000
