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.
