Limit the bandwidth of Audio and Video
User Configuration\Administrative Templates\Windows Components\NetMeeting\Audio&Video
Limits the bandwidth audio and video will consume when in a conference. This setting will guide NetMeeting to choose the right formats and send rate so that the bandwidth is limited.
The NetMeeting folder containing this policy is created by the Conf.adm administrative template. Conf.adm is included in Windows 2000, but does not load in Group Policy automatically. To display the NetMeeting folder, add the Conf.adm administrative template to Group Policy.
