3What Is NetMeeting?
NetMeeting enables you to communicate with others
over the Internet or your local intranet. Using
NetMeeting you can
- Use data conferencing tools between an unlimited
number of participants - Use audio and video between two people
- Share and collaborate on applications
- Use tools such as chat, whiteboard, and file
transfer - Control the desktop remotely
4NetMeeting Technology
- Microsoft NetMeeting is a VoIP and multi-point
videoconferencing client included in many
versions of Microsoft Windows (from Windows 95
OSR2 to Windows XP). It uses the H.323 protocol
for video and audio conferencing, and is
interoperable with OpenH323-based. It also uses
a slightly modified version of the ITU T.120
Protocol for whiteboarding, application sharing,
desktop sharing, remote desktop sharing (RDS) and
file transfers. The secondary Whiteboard in
NetMeeting 2.1 and later utilizes the H.324
protocol.
5NetMeeting Technology
- NetMeeting is a software application for audio
and video conferencing. NetMeeting offers sharing
of desktop video, audio, chat and file transfer
functionality. - NetMeeting supports directory servers and
services. NetMeeting uses may automatically
register with a directory when they start their
NetMeeting client. The directory then allows
users to find online users by name or location.
If no directory is available, NetMeeting users
can also call each other directly by computer
name or IP address. - Once connected to other users, NetMeeting places
all parties in a "call." NetMeeting tracks the
call roster and allows users to share their
desktop windows, to chat, transfer files, or
share a VoIP feed.
6Voice Over Internet Protocol
- VoIP is a technology that allows telephone calls
to be made over computer networks like the
Internet. VoIP converts analog voice signals into
digital data packets and supports real-time,
two-way transmission of conversations using
Internet Protocol (IP).
7Voice Over Internet Protocol
- VoIP calls can be made on the Internet using a
VoIP service provider and standard computer audio
systems. Alternatively, some service providers
support VoIP through ordinary telephones that use
special adapters to connect to a home computer
network. Many VoIP implementations are based on
the H.323 technology standard.
8Voice Over Internet Protocol
- VoIP offers a substantial cost savings over
traditional long distance telephone calls. The
main disadvantage of VoIP is, like cell phones, a
greater potential for dropped calls and generally
lesser voice quality.
9H.323 Protocol
- H.323 is a protocol standard for multimedia
communications. H.323 was designed to support
real-time transfer of audio and video data over
packet networks like IP. The standard involves
several different protocols covering specific
aspects of Internet telephony. The International
Telecommunication Union (ITU-T) maintains H.323
and these related standards.
10H.323 Protocol
- Most voice over IP (VoIP) applications utilize
H.323. H.323 supports call setup, teardown and
forwarding/transfer. Architectural elements of a
H.323 based system are Terminals, Multipoint
Control Units (MCUs), Gateways, an optional
Gatekeeper and Border Elements. Different
functions of H.323 run over either TCP or UDP.
11OpenH323 PROTOCOL
- Full featured, open source implementation of the
H.323 Voice over IP protocol. The code is written
in C and, through the development effort of
numerous people around the world, fully supports
the H.323 protocol. The software has been
integrated into a number of open source and
commercial software products.
12ITU T.120 PROTOCOL
- ITU-T recommendation that describes a series of
communication and application protocols and
services that provide support for real-time,
multipoint data communications. It is used by
products such as Cisco WebEx's MeetingCenter,
Microsoft NetMeeting and Lotus Sametime to
support application sharing, real-time text
conferencing and other functions.
13Transmission Control Protocol
- Transmission Control Protocol (TCP) and Internet
Protocol (IP) are two distinct network protocols,
technically speaking. TCP and IP are so commonly
used together, however, that TCP/IP has become
standard terminology to refer to either or both
of the protocols. - IP corresponds to the Network layer (Layer 3) in
the OSI model, whereas TCP corresponds to the
Transport layer (Layer 4) in OSI. In other words,
the term TCP/IP refers to network communications
where the TCP transport is used to deliver data
across IP networks. - The average person on the Internet works in a
predominately TCP/IP environment. Web browsers,
for example, use TCP/IP to communicate with Web
servers.
14UDP Protocol
- UDP is a lightweight transport built on top of
IP. UDP squeezes extra performance from IP by not
implementing some of the features a more
heavyweight protocol like TCP offers.
Specifically, UDP allows individual packets to be
dropped (with no retries) and UDP packets to be
received in a different order than they were
sent.

30How to establish a connection through a firewall
- To establish outbound NetMeeting connections
through a firewall, the firewall must be
configured to do the following - Pass through primary TCP connections on ports
522, 389, 1503, 1720 and 1731 - Pass through secondary UDP connections on
dynamically assigned ports (1024-65535).
31How to make a video call with Net Meeting
- To receive video, all of the following conditions
must exist - There must be a user capable of sending video.
- The user capable of sending video must be sending
video to you. - If you are receiving the video, the status in the
video window should read "Receiving." If the
status reads "Paused," you will not receive live
video until you click the Play button to resume
play.

- Making an Audio and Video Connection
- NetMeeting establishes a video connection
automatically at the beginning of the call if the
Automatically send video at the start of each
call check box is selected. - If you are in a data conference and do not have
an audio and video connection established, you
can right-click a user on the Current Call tab,
and then click Switch Audio And Video. - You can also click Switch on the toolbar, and
then click to select the user with whom you want
to establish an audio and video connection. Note
that the Switch button is available only when the
Current Call tab is selected.
34How to Share programs in Net Meeting
- NetMeeting allows you to share programs running
on your computer with other NetMeeting
participants. Programs can be shared even when a
participant does not have that program installed
on his or her computer. - When you are in a NetMeeting conference, others
in the conference can see and use a program
running on your computer.
35How to Share programs in Net Meeting
- To share a program within NetMeeting, click the
Tools menu, point to Share Applications, and then
click the program to share. Or, you can click the
NetMeeting icon on the taskbar, point to Share
Application, and then click the program you want
to share. Or, you can click the Share button on
the toolbar displayed for the current call. - When you select a program, it is seen on every
other computer in the conference. The name of the
program's owner is displayed in the upper- right
corner of the window (if that window is not
maximized). - By default, you are in control of the program.
You can click Collaborate on the Tools menu, or
click the Collaborate button on the toolbar for
the current call, to allow others to use the
program. In this mode, the initials of the
participant who has control are added to the
mouse pointer. Any user can change or run your
program after taking control of the program by
double-clicking the shared program.
36How to Share programs in Net Meeting
- Program sharing is achieved by passing graphics,
mouse movements, and keyboard inputs to the other
computers in real time. Your color and resolution
settings have an impact on how items are
displayed on other computers. If the originator
of the shared program is using 1024 x 768 screen
resolution, but a participant is using 640 x 480
resolution, the participant's screen will be too
small to display the whole window.
37How to transfer files in Net Meeting
- When you are in a NetMeeting conference, you can
transfer a copy of a file to every participant in
the conference. - You can transfer a file by dragging the file's
icon to the NetMeeting window for global file
transfers (transfers to all conference members),
or by pointing to a single participant. To
initiate a global file transfer, you can also
click File Transfer/Send File on the Tools menu. - You can initiate individual file transfers by
right-clicking a participant in the roster and
then clicking Send File. In most cases, you see
the Browse dialog box. If you use the drag
method, no dialog box is visible.
38How to use chat in Microsoft Net Meeting
- NetMeeting includes a Chat tool that allows
online meeting participants to communicate with
each other using standard text messages. Chat is
particularly useful when one or more meeting
participants is unable to use the audio features
of NetMeeting. - To start Chat, click Chat on the Tools menu in
NetMeeting, click the Chat button on the toolbar,
or click the Chat icon on the menu from the
NetMeeting icon on the taskbar.

- When one person in a meeting runs Chat, it
appears on all screens. Everyone in the meeting
can then type messages simultaneously and see
what other people are typing. - You can specify the font and font size, style,
and effects that are used for the messages and
information display in the Chat window on your
computer. - You can specify the items included in the
information display associated with each message
in the Chat window and the format used for the
messages. - You can save the current contents of the Chat
window so they can be opened in NetMeeting,
Microsoft Excel, or another spreadsheet or word
processing program in the future.

43Where is NetMeeting going today?
- NetMeeting helped pioneer online conferencing
when it was released in May 1996, before the
advent of instant messaging (IM) and other
services for real-time online communication. - The software still ships as part of Windows and
some of its features, such as whiteboarding and
application-sharing, are used by the MSN
Messenger and Windows Messenger IM applications.
44Future of NetMeeting
- NetMeeting is no longer included with Windows
Vista, and has been replaced by Windows Meeting
Space and Microsoft office Live Meeting. - However, a hot fix for Vista was published by
Microsoft on March 22, 2007. - The hot fix contains an installer package to
install NetMeeting 3.02 on Windows Vista
business, enterprise or ultimate versions.
Version 3.02 is essentially a port of 3.01 to
Vista. Net meeting doesn't work with Vista Home
edition.
45Future of NetMeeting
- NetMeeting can still be installed and run on
Windows Vista. A hotfix for Vista was published
by Microsoft on March 22, 2007 can obtain this
hotfix by contacting Microsoft Support. The
hotfix contains an installer package to install
NetMeeting 3.02 on Windows Vista business,
enterprise or ultimate versions. Version 3.02 is
essentially a port of 3.01 to Vista. Netmeeting
doesn't work with Vista Home edition.
46Future of NetMeeting
- Microsoft plans to phase NetMeeting out and
remove it from its Web site. The NetMeeting
directory is already gone, which means that users
have to type in the IP address of the person they
want to conference with or use another online
directory service. There is no time-frame for
the NetMeeting phase-out. It appears that it
will be a gradual transition. - Many businesses still use NetMeeting, although
IM and Web conferencing products outclass it in
terms of usability, analysts said.
47Future of NetMeeting
- Before video service became common on free IM
clients, such as Yahoo! Messenger and MSN
Messenger, NetMeeting was a popular way to
perform videoconferences and chatting over the
Internet (with the help of public ILS servers, or
"direct-dialing" to an IP address). - Since the release of Windows XP, Microsoft has
deprecated it in favor of Windows Messenger and
Microsoft Office Live Meeting, although it is
still installed by default (Start Run...
C\Program Files\NetMeeting\conf.exe). Note that
Windows Messenger, MSN Messenger and Windows Live
Messenger hooks directly into NetMeeting for the
application sharing, desktop sharing, and
Whiteboard features exposed by each application.
