What is Netmeeting?
Netmeeting is a conferencing client developed by Microsoft that allows users to interact in real time
over the internet. Most people call it a "video conferencing client", but it is actually capable of much
more than that. Ìt includes:
O A Chat client, similar to AOL Ìnstant Messenger
O An Audio and Video conferencing client
O A Whiteboard, which is a shared drawing space where people can collaborate in real time.
O Application Sharing, where you can choose to share an application you are running with
others in your conference. Note here that while other users will need to have Netmeeting
installed, they do not need to have a copy of the application you are sharing installed.
O A file transfer application for sending files
What Do I Need?
A PC running a Windows variant, such as Windows 95, Windows 98, Windows NT 4.0, Windows
2000 or Windows XP. You should have Ìnternet Explorer 4.0 or better installed as well. Note that
Windows XP and 2000 come with Netmeeting already installed.
The PC should a reasonably current machine, such as a Pentium ÌÌ 233 MHZ or better. A slower
machine may work, but audio and video performance will suffer. Ìt should have a decent amount of
Ram (64 MB or better). A sound card is not mandantory, but for audio conferencing, some sort of
audio interface is necessary.
Netmeeting uses the Videoconferencing standard .h323. There are other products that use this
standard as well, including a solution for Macintosh users. See the section "For Mac Users" at the
end.
Microphone and Headphones
Ìf you want to participate in an audio conference, you need a microphone. You need not spend a lot of
money. A inexpensive SoundBlaster compatable (this is important) microphone (less than $10.00)
and a inexpensive pair of headphones (like the kind that can be used with a Walkman) is all you need.
You can also opt for a headset that has the microphone built in; this is all a matter of preference.
Using headphones instead of a pair of speakers is preferred, since the microphone will pick up what is
coming over the speakers, and will lead to a strange, and disconcerting "echo" effect.
Network connection
While it is possible to use some functions in NetMeeting with a 56k modem, a faster network
connection is preferable. For Video or screen sharing, use at least a Dual ÌSDN connection (112 kbs).
A Cable Modem or DSL connection is perfectly adequate for any of the features in NetMeeting when
at home. Most campuses have at least 10 mb/s connections, which is good enough to do decent low
frame rate video and good audio, as well as all the other features in NetMeeting.
There are some additional issues concerning use of NetMeeting iin special situations, such as with a
firewall, or through a home networking router. A brief outline on the issues is being written, and will
appear shortly.
%he Software
You will need the Netmeeting software itself. Ìf you are currently running Windows 2000 or XP, you do
not need to install it; it comes with the standard install. Under Windows XP, you may need to "unhide
Netmeeting to launch it directly:
o to your Start menu and select "run". Type in "conf.exe" (no quotes). The Netmeeing setup wizard
will then start, and ask you whether you would like shortcuts created (yes you do).
For Windows 2000, look in your Start menu under Accessories/Communication to launch it. You
should also confirm that you have at least version 4.0 of Ìnternet Explorer installed
8.4393:0/
As oI Windows Vista, NetMeeting is no longer included with MicrosoIt Windows, and MicrosoIt recommends
using newer applications such as Windows Meeting Space, Remote Desktop Connection, Remote Assistance,
Windows Live Messenger and MicrosoIt OIIice Live Meeting in place oI NetMeeting.
