When you have multiple locations with multiple people all in one meeting, it's helpful to have a host at each location, as well as a main host for the meeting. For optimal performance in these situations, participants should connect to the host at their location, and then the distributed hosts should connect to the main host. The person to whom the participants connect when they join the meeting. Typically, the host is the also the person running the meeting. Participant Anyone who participates in the meeting, but is not the host.
Participants can still share documents and collaborate.
Sharing When you allow people to see a particular application that is installed on your computer. To share an application, click the Share button in the NetMeeting toolbar, and then select the application from the list. Once you do this, everyone in the meeting will be able to see the application, as well as any changes that you make, as you make them. You must have the application running in order to share it.
