SYSTEM REQUIREMENTS AND SETUP
=============================
Microsoft(R) NetMeeting(R) enables real-time audio, video, and
data communication over the Internet.
In order to use Microsoft NetMeeting, you must have the
following configuration:
- Microsoft Windows(R) 95 or Windows(R) 98
- At least a 486/66 processor with 8 megabytes of RAM
(Pentium with 12 MB of RAM recommended)
--or--
- Microsoft Windows NT(R) version 4.0
- At least a 486/66 processor with 16 megabytes of RAM
- Microsoft Windows NT 4.0 Service Pack 3 required to enable
sharing applications on Windows NT
IMPORTANT NOTES:
* NetMeeting does not run on Windows version 3.1 or beta
versions of Windows 98 older than Beta 3.
* It is strongly recommended that you uninstall earlier beta
versions of Microsoft NetMeeting before installing NetMeeting
2.1.
- If you use special characters, such as "\\" or double-byte
characters, when typing the installation location for NetMeeting
during setup, NetMeeting may not install correctly.
- NetMeeting no longer supports placing calls over IPX or over
PSTN.
- NetMeeting works best with a fast Internet connection (a 28.8k-
baud or faster modem or a local area network).
- To use the audio features of NetMeeting, you need a sound card,
speakers, and a microphone.
- To send video with NetMeeting, you need either a video-capture
card and camera or a video camera that connects through your
computer's parallel (printer) port. You will not be able to
send video on some computers with a processor slower than a
Pentium.
Computers with a bidirectional (ECP or EPP) parallel port will
perform noticeably better with parallel port video cameras than
computers with a unidirectional parallel port.
Cameras that connect to a video-capture card will use less of
your computer's processor than cameras that connect through your
computer's parallel port. It is recommended that you do not use
a color parallel port camera unless your computer is at least a
Pentium 133.
- The application-sharing feature may not perform well while you
are using audio and video and are connected over a slow
connection. Additionally, you might experience "choppy" audio
while using video.
The default setting for video over a 28.8-baud modem connection
is medium quality. To change this setting, click the Tools menu,
click Options, click the Video tab, and then change the Video
Quality option.
- Windows NT users will be able to share applications if they have
installed Service Pack 3 for Windows NT 4.0.

USING MICROSOFT NETMEETING
==========================
- Microsoft NetMeeting includes support for the H.323 audio
and video conferencing standard. NetMeeting can be used to
place calls to and receive calls from products that are H.323-
compatible, including the Intel Internet Video Phone. With
appropriate equipment and services that are currently under
development by third parties, NetMeeting can place a call to
a telephone using an H.323 gateway.
- Microsoft maintains the following directory servers on the
Internet:
ils.microsoft.com
ils1.microsoft.com
ils2.microsoft.com
ils3.microsoft.com
ils4.microsoft.com
ils5.microsoft.com
You can use one of these even if it does not appear in the list
of servers in the wizard.
You can also use the following directory servers not maintained
by Microsoft:
ils.four11.com
ils.business.four11.com
ils.family.four11.com
NOTE
* You will not be able to use these servers to locate people on
the Internet if you connect to the Internet through a proxy
server that does not support Remote WinSock.
- Audio and video work only over TCP/IP and with one other person
at a time.
- If you use this version of NetMeeting to call someone who
is using NetMeeting 2.0, the call-switching feature may not work
correctly.
- This version of NetMeeting enables up to 32 users to share an
application. However if a computer running NetMeeting 2.0 is in
the conference and more than three users are sharing, that computer
will not be able to host an application. In addition, you can be
connected to only one other person with audio and video at a time.
The total number of people who can successfully participate
in your meeting will vary based on available network bandwidth
and the speed of the participants' computers.
- Some activities cause large amounts of data to be sent between
the computers in your meeting (for example, speaking and sharing
several applications while transferring a large file). In extreme
cases, this might cause computers in the meeting to become very
slow. To remedy this, stop one or more of the meeting activities.
- If you try to make a TCP/IP call on your local area network or
through a proxy server and MSN or Dial-Up Networking displays a
connection dialog box, you can disable this by clicking the
Internet icon in Control Panel and then making sure that Auto-
Dial is not selected.
- Sharing of DirectX, OpenGL, MS-DOS(R), and graphics-intensive
games and AVIs does not work well and is not supported.
- If different computers have different screen resolutions during
a meeting, the shared windows can be as large as the highest
resolution desktop allows. Users with lower resolution desktops
must scroll to view windows that don't fit their screens.
- You must have a 32-bit TCP/IP stack and Windows sockets
interface to use NetMeeting with TCP/IP. NetMeeting has
been tested with the 32-bit TCP/IP and Windows sockets built
into Windows 95 and Windows NT version 4.0.
- Application-sharing, Whiteboard, and Chat might not work
properly between computers with different language settings
and keyboard layouts.
- Microsoft NetMeeting supports using Windows 95 and Windows NT
version 4.0 system policies to set default configurations in
a corporate environment.
Microsoft NetMeeting system policies are documented, and a
system policy file is included in the NetMeeting Resource Kit.
For more information about the NetMeeting Resource Kit, see
http://www.microsoft.com/netmeeting/reskit.
- If NetMeeting hangs when it starts, check to see whether
there are damaged fonts in your Fonts folder.
- If you are using Internet Explorer 4.0 in Offline mode and
you try to start NetMeeting, NetMeeting will not automatically
connect to the Internet. To work around this problem, dial
up using RAS (for Windows NT computers) or Dial-Up Networking
(for Windows 95 computers). Or, in Internet Explorer, click the
File menu, and then click Work Offline to clear the check mark.
- NetMeeting does not function properly over SLIRP connections
or other simulated SLIP/PPP connections.
PLACING A CALL
==============
You can place Microsoft NetMeeting calls to multiple users. Any
person in a meeting can place NetMeeting calls to other people.
In addition, other people can join a NetMeeting call in progress
by calling one of the participants.
Warnings and Known Bugs
-----------------------
- If you cannot connect to someone by using their computer name,
try using their IP address.
- If you click someone's name in the Web directory and get a
message asking whether you would like to open or save the file,
select open file.
- If you click someone's name in the Web directory and get a
message saying that the file type is unrecognized, you need
to configure your browser to associate the ILS directory files
with Microsoft NetMeeting.
For instructions on how to do this, refer to your browser
documentation. You will need the following information:
MIME file type: "text/iuls"
Command line: "rundll32.exe msconf.dll,NewMediaPhone %l"
MIME file type: "text/h323"
Command line: "rundll32.exe msconf.dll,NewMediaPhone %l"
- Some ISDN devices are configured to automatically connect to
the network. This might cause the ISDN device to try to connect
to the network while NetMeeting is running. To stop this from
happening, turn off Auto-Dial on the ISDN device.
- If you do not see your name in the directory, you might not be
logged on, or you might be logged on to a different directory
server. To change the directory server you log on to, click the
Tools menu, click Options, click Calling, and then change your
Server Name.
To log on to the directory server, click the Call menu, and
then click Log On To [your directory server].
- If you have an active network connection using a network card
and a second active connection using a second network card,
you might not be able to connect to the directory.
- If you experience connection problems when dialing via a null
modem connection, try lowering the baud rate for your modem.
- Some conference bridges (also known as Multipoint Conferencing
Units, or MCUs) are case-sensitive, so when you type the
conference name to place a call, you may need to use the same
capitalization as that shown on the bridge.
- To receive calls over a null modem cable, click the Tools menu,
click Options, and then click the Protocols tab. Select the
Null Modem protocol, and then click Properties. Select the COM
port to which the null modem cable is connected.
- NetMeeting does not detect incoming calls on a COM port to
which a null modem cable is connected. To receive calls over
a null modem cable, you must place a call on the COM port.
- Changes made to the COM port properties in NetMeeting apply
only in NetMeeting. It is recommended that you do not change
the COM port settings while you are placing or participating
in a NetMeeting call.
- NetMeeting uses the COM port typed into the New Call dialog box
to place the call, not the COM port specified in the Null Modem
Protocol Properties dialog box.
- NetMeeting can use only COM1 and COM2 to place and receive null
modem calls.
- Null modem calls at high baud rates may not work.
- If you connect to someone through a proxy server, you may need
to manually connect audio and video after joining the call.
RECEIVING A CALL
================
You are ready to receive incoming calls if you are running
Microsoft NetMeeting and have not selected Do Not Disturb on
the Call menu.
Warnings and Known Bugs
-----------------------
- If you are not able to receive calls, it may be because your IP
address is registered incorrectly with the directory service.
You can prevent this by releasing the LAN IP address before
connecting to the Internet. To release the IP address, do the
following:
On Windows 95 Click the Start menu, click Run, and
then type Winipcfg.exe
On Windows NT Click the Start menu, click Run, and
then type Ipconfig /release
SHARING AN APPLICATION
======================
Any person in a meeting can share an application with the other
participants. When you share an application, other people can
see the application. When you Collaborate, other people can both
see and use the application.
Warnings and Known Bugs
-----------------------
- Windows NT users will be able to share applications if they
have installed Service Pack 3 for Windows NT 4.0.
- If NetMeeting is installed in a directory where the path
contains extended characters, application sharing might not
work.
- Sharing one Windows Explorer window shares all of them. If you
run a program while sharing Windows Explorer, the program will
also be shared.
Examples of Windows Explorer windows include Control Panel,
Briefcase, the Received Files folder, or any Windows Explorer
folder.
- Internet Explorer 4.0 users: If you share a Windows Explorer
window, with collaboration enabled, and the person with whom
you are collaborating closes the window, all applications and
windows that you open afterwards will be shared.
To undo sharing in this situation, open a Windows Explorer
window again, and un-share it.
- When you share an application and collaborate, remote users
can use the File Open and File Save dialog boxes in your
application to gain access to or delete files on your computer
or network.
To stop someone from using your shared program while you do
not have control of the cursor, press ESC.
To stop someone from using your shared program while you do
have control of the cursor, click the Stop Collaborating
button.
It is recommended that you do not leave your computer unattended
while sharing an application and collaborating.
- When you launch another application from within the application
you are sharing (such as a Microsoft Excel spreadsheet from
within Microsoft Word), there's a possiblity that the recently
launched application won't be shared properly.
- You cannot drag an object onto a shared application or drag an
object from a shared application to the desktop.
- When you share an application with an Input Method Editor
(IME), you should show the IME status bar so that other
people can use the mouse to activate the IME.
If the IME does not support showing the status bar, or if other
people are having trouble activating the IME, you should
activate and deactivate the IME for them.
- If the IME window fails to repaint during a meeting, you can
cause it to repaint by clicking anywhere on the desktop.
- You may not be able to share applications on a computer with a
product installed that has application sharing or remote
control features.
WHITEBOARD
==========
The Whiteboard enables you to draw simultaneously with other
people. Everyone in the meeting can see what is drawn on the
Whiteboard. When one person in a meeting runs Whiteboard, it
appears on everyone's screen.
Warnings and Known Bugs
-----------------------
- On a computer running Windows NT, if the directory in which
NetMeeting is installed contains spaces in its name, you
will not be able to run Whiteboard or Chat.
- Whiteboard does not maximize to the full size of an 1152 by
864 or larger display.
CHAT
====
Chat enables you to type messages for other users to see. When
one person in a meeting runs Chat, it appears on everyone's
screen.
Chat files are stored with the .txt file extension. If Microsoft
Notepad, or another program that can read files in .txt format,
is installed on your computer, it can be used to open Chat files.
Warnings and Known Bugs
-----------------------
- On a computer running Windows NT, if the directory in which
NetMeeting is installed contains spaces in its name, you will
not be able to run Whiteboard or Chat.
FILE TRANSFER
=============
- Files dragged onto the list of people on the Current Call tab
are sent to all the people in the meeting.
- To send a file to a specific person, right-click that person's
name in the list of people in the meeting, and then click Send
File.
- To send a file to everyone in the meeting, click the Tools
menu, click File Transfer, and then click Send File.
Warnings and Known Bugs
-----------------------
- If you try to send a shortcut to a file, the actual file will
be sent instead.
- Exchanging files with Intel ProShare 2.0 does not always work
properly.
AUDIO COMMUNICATION
===================
- Audio is supported only over TCP/IP and with one other person.
- Sound quality can vary significantly depending on your sound
card and microphone.
- Using full-duplex audio can require both more bandwidth and
more CPU than using half-duplex audio, and therefore may result
in poor sound quality.
- If you modify your sound card device driver in any way, such
as upgrading to a full-duplex driver, you will need to run the
Audio Tuning Wizard again in order for NetMeeting to work
correctly.
Warnings and Known Bugs
-----------------------
- If you are using a Videum (Winnov) video-capture card and
have the new 2.0 drivers, you can change the audio input for
the card by opening the Videum Configure program (under the
Winnov Videum program group) and selecting the desired audio
input for the video input being used with Netmeeting. The default
is to use the Camera microphone for the MXC video connection
and Line Input for all other video connections. After you do
this, the correct audio input will be selected when you start
NetMeeting.
- Audio input for users of Winnov cameras will automatically be
switched whenever video is in use. If your video is connected
using the MXC connection, the camera input will be used for
audio. If your video is connected using the Composite or
S-Video connection, the Line Input will be used for audio.
You can solve this problem by upgrading to the new 2.0 drivers
and by using the Videum Configuration application.
- Users of Microsoft NetMeeting and Intel Internet Video Phone
can talk to each other only if both users have a computer with
a Pentium processor.
- If you have a SoundBlaster sound card with full-duplex sound
enabled, and you have problems with your computer locking up
when using NetMeeting, you may need to update your Sound-
Blaster drivers.
- You may receive a message in the Audio Tuning Wizard that
explains that your sound card is unsupported. This occurs when
the sound card does not support some of the features required
for it to be supported by NetMeeting. The audio features in
NetMeeting may work even if you get this message, but you might
experience poor audio quality.
If your sound card is unsupported, you might want to contact
the manufacturer to find out if newer sound card drivers are
available.
- If you are experiencing "choppy" full-duplex sound quality, try
switching NetMeeting to half-duplex sound quality. To do this,
carry out the following steps:
1. Make sure that you are not in a NetMeeting call.
2. On the Tools menu, click Options.
3. On the Audio tab, clear the Enable Full Duplex Audio check
box.
It is recommended that you not switch between full-duplex and
half-duplex audio while in a meeting with audio.
- If you are having problems with your audio quality or sound
card when using NetMeeting, the problems could be related to
your hardware configuration or driver installation. To see
the latest support information, click the Help menu, and then
click Online Support.
- If your computer has more than one audio device, you should
make sure that the audio devices selected in the Audio Tuning
Wizard match the selections in the Multimedia properties in
Control Panel.
- If you upgrade your computer's processor, you should re-run
the audio tuning wizard.
- Full-duplex audio might not work with Media Vision Pro Audio
Spectrum 16 sound cards.
- Computers with a 486 processor will not be able to use audio
with other software based on the H.323 audio conferencing
standard over a Dial-Up Networking (modem) connection. They
will be able to use audio with other NetMeeting users over
a Dial-Up Networking connection or with other H.323-based
audio conferencing products over a local area network (LAN).
- When you are in an audio conference using NetMeeting, an
application that has the ability to record sound, such as
Microsoft PowerPoint, will appear to be recording sound
as instructed. However, since NetMeeting is already using
the sound card, the other application is not actually
recording.
- If you have a Tecra 740, you may need to manually set
the microphone volume level in the Multimedia properties
in Control Panel.
- If you experience poor audio quality, try clearing the
Microphone check box and then selecting it again.
- If you are using a Gravis Ultrasound sound card and you
are experiencing choppy audio quality, try the following:
1. Make sure that you are not in a NetMeeting call.
2. On the Tools menu, click Options.
3. On the General tab, in the Network bandwidth section,
select a bandwidth setting that is slower than the
current selection.
HANGING UP
==========
When you hang up, you disconnect anyone you called or anyone
who called you. If the disconnected users have invited or
accepted other users into the meeting, they are also disconnected.
Audio connections between people might not be disconnected.
Warnings and Known Bugs
-----------------------
- If you are using a 56 kps modem in a NetMeeting call with two
or more other people, hanging up may not work correctly.
Switching audio and video during the call may also cause one
or more participants to be disconnected.
VIDEO
=====
- To use the video features of NetMeeting, you need either a
video-capture card and camera or a video camera that connects
through your computer's parallel (printer) port. Sending video
does not work on some computers that have a processor slower
than a Pentium.
- Video is supported only over TCP/IP and with only one other
person at a time.
- Running video in a multiuser meeting can negatively impact
performance on all the computers in the meeting. For example,
opening a video window while sharing an application can make
it difficult for others to take control of the application.
- If you have more than one video device installed, or you have
not properly uninstalled a video device that was previously
installed, you might not be able to use video.
- If your video device is not properly uninstalled and you have
enabled video in NetMeeting, the remaining camera software
may warn you repeatedly that it cannot find the camera.
- If your computer's processor is slower than a Pentium, sending
video may result in poor audio and video quality.
- Computers with a bidirectional (ECP or EPP) parallel port will
perform noticeably better with parallel video cameras than
computers with a unidirectional parallel port.
- Cameras that connect to a video-capture card will use less of
your computer's processor than cameras that connect through
your computer's parallel port. It is recommended that you not
use a color parallel port camera unless your computer is at
least a Pentium 133.
- If you disconnect your camera while using the video features
in NetMeeting, your camera's software may display messages
telling you that the camera is not responding. To disable
these messages, click the Tools menu, click Options, click
Video, and then clear the Automatically Send Video At The
Start Of Each Call check box.
- It is recommended that you not run another program that uses
video while running NetMeeting.
- If some areas of your video window contain the wrong colors,
your camera might be aimed at an area with insufficient light.
Some video drivers might provide a low-light filter option.
- If you are using the video features in a dark area, some
cameras will cause your computer to become extremely slow
and unresponsive.
- If you use a Black and White Connectix Camera, it is
recommended that you use the version 2.1 update (or newer)
of the video drivers. You can download drivers from
http://www.connectix.com.
- Audio input for users of Winnov cameras will automatically be
switched whenever video is in use. If your video is connected
using the MXC connection, the camera input will be used for
audio. If your video is connected using the Composite or
S-Video connection, the Line Input will be used for audio.
- With some cameras, you may be able to reduce CPU usage by
manually adjusting the settings in the Source and Format
dialog boxes instead of letting the video driver software
do it automatically.
GENERAL KNOWN ISSUES
====================
- You cannot run ReachOut 5.0 on computers on which Microsoft
NetMeeting is installed.
- To find the name that NetMeeting uses as your NetBIOS name,
carry out the following steps:
1. In Control Panel, click the Network icon, and then click the
Identification tab.
2. Select the Computer Name text box.
- If you use User Profiles for multiple users to maintain your
Windows preferences on all the computers on a network, you
might have to run the Audio Tuning Wizard again when you switch
computers.
- Both Microsoft FrontPage and Microsoft NetMeeting currently use
the same file type (.cnf). NetMeeting uses this file type for
Speed Dials.
- When you are in a meeting, your Clipboard is shared with
everyone else in the meeting. This enables you to paste objects
other people cut or copy to the Clipboard into your local
programs. You can set a system policy that disables Clipboard
sharing.
- If you are running Windows 95 Version 4.00.950B, and you cancel
the Dial-Up Networking dialog box that appears when you start
NetMeeting, NetMeeting appears to stop responding; however,
NetMeeting will work properly after about two minutes. However,
you will not be logged onto the directory server until you manually
connect to your Internet service provider and then on the Call
menu, choose Log On To [your directory server].
- If you create a SpeedDial shortcut, clicking Send To Mail
Recipient will work only if your e-mail program is MAPI-aware
(for example, Microsoft Outlook Express).
- You can return calls by using the History tab only if
the person who called you was using NetMeeting 2.0 or
NetMeeting 2.1.
- If you are using NetMeeting over a 28.8 kbp connection, you may
be able to get better audio and video quality by clicking the
Tools menu, clicking Options, and then choosing ISDN or Local
Area Network from the Network Bandwidth section.
WINDOWS NT ISSUES
=================
- If you use Windows NT, you will be able to share applications
if you have installed Service Pack 3 for Windows NT 4.0.
- Enabling Application Sharing on Windows NT may negatively
affect the performance of your display driver. This will affect
the rate at which information is drawn on the screen.
- Some Creative Labs SoundBlaster drivers (specifically those
posted on their Web site January 15, 1997) are not compatible
with NetMeeting. SoundBlaster drivers that come with Windows
NT 4.0. do work with NetMeeting, as do the more recently
posted drivers, which also support full-duplex audio.
- If you use Windows NT, you will experience problems if
you share a 32-bit application and then insert an object
that is a package. This opens the Object Packager, which is
automatically shared and will subsequently fault. This fault
will not cause the original shared application or NetMeeting
to fault, only the Object Packager.
- If you enabled the floating point workaround during
installation of Windows NT on a computer that is equipped
with a flawed Intel Pentium chip, NetMeeting audio quality
will be poor, or audio will not work at all.
- When you share a 16-bit application, all the 16-bit applications
that are running on your computer will also automatically be
shared.
- If you are using NetMeeting on Windows NT and you are unable to
receive a call, restart your computer and try again.
- If you do not have a sound card, you will need to manually
specify the bandwidth of your connection. To do this, click
the Tools menu, click Options, and then click Network Bandwidth.
- You may need to uninstall Dial-Up Networking in order to log
on to a Directory Server via a proxy.
- If, after placing a call, you see a message for more than one
minute that NetMeeting is waiting for a response from the
other person, quit NetMeeting and then try to contact the
person again.
- If you are unable to see a video image in NetMeeting, it is
recommended that you upgrade to DirectDraw 3.0 or newer.
- If you suspend your computer, or if it is set to suspend
automatically, you should quit and then restart NetMeeting
after resuming.
- If you receive a SpeedDial in an e-mail message, your mail
program may convert it to a text (.txt) file. You will be
able to use it as a SpeedDial if you rename it with a .cnf
extension.
