Enable Automatic Configuration

Configures NetMeeting to download settings for users each time it starts. The settings are downloaded from the URL listed in the “Configuration URL:” text box. Group Policy based settings have precedence over any conflicting settings set by downloading them from this URL.

Download missing COM components

This policy setting directs the system to search Active Directory for missing Component Object Model (COM) components that a program requires. Many Windows programs such as the MMC snap-ins use the interfaces provided by the COM components. These programs cannot perform all their functions unless Windows has internally registered the required components. If you enable this policy setting and a component registration is missing the system searches for it in Active Directory and if it is found downloads it. The resulting searches might make some programs start or run slowly. If you disable or do not configure this policy setting the program continues without the registration. As a result the program might not perform all its functions or it might stop. This setting appears in the Computer Configuration and User Configuration folders. If both settings are configured the setting in Computer Configuration takes precedence over the setting in User Configuration.

Prevent Control

Prevents users from allowing others in a conference to control what they have shared. This enforces a read-only mode; the other participants cannot change the data in the shared application.
