1. Obtaining, Installing, Setting up, and Logging onto classrooms with  NetMeeting

(Since Schola operates on Escondido Tutorial Service's reflector server, and because a number of students take tutorials from both ETS and Schola, we (and also Oxford Classical Tutorials) follow ETS's technical protocols for the sake of consistency.)
1. If you have Windows XP, you have NetMeeting on your computer already. If you have Windows XP you should NOT download Netmeeting, but use the version which comes with Windows XP.  Go to Start | My Computer | C: | Progam Files | NetMeeting and double click Conf.exe to start NetMeeting.  If you have trouble finding it, go to Start | Search | All files and folders, then in the "all or part of the file name" box, type "NetMeeting". When you find it, note its location in your computer's directory (if the search box doesn't show the directory, then click "view" at the top of the search window, then click "details").  If you do not have NetMeeting, go to Microsoft's NetMeeting download page  and follow the simple directions to download the software. The first time you run NetMeeting, you'll be given the option of having a shortcut installed on your desktop so it'll be easy to find and start from then on, and it will ask you for some basic setup information. 

2. Start NetMeeting if it's not already started. Go to the main NetMeeting window, go to tools | options | audio and run the audio tuning wizard.  Make sure the "enable full-duplex" box is UNchecked. Go to the general tab and click on the Bandwidth settings button and set to 28,800 or faster.

3. To connect to the classroom, go to start | Programs | NetMeeting (or double-click your desktop icon) to start NetMeeting. In the drop-down box at the top of the NetMeeting window, type in the IP address of the conference server (this will be sent to you by email) and click on the phone button. A box will pop up showing the "classrooms" you can join--select the "3 Callihan" room and click "OK". Now click on View at the top of the main NetMeeting window and make sure compact and Data only are unchecked.  Then make sure that your mic is OFF by clicking the speaker/mic button in the middle of the main NetMeeting window until a picture of a face appears instead of the speaker/mic image and then UNchecking the mic box beneath it.  The chat window will already be open unless you're the very first person in the room--if that's the case, just click the chat button (second from left at bottom of main NetMeeting window, with the chat balloon picture) to open the chat box.

Note to users of DSL and Cable modems:

If you are using DSL or Cable and/or a router, it is desirable that the computer which you are using for class has its own IP address.   Having a Proxy IP address on your computer or having a firewall on the router or broadband modem may cause Netmeeting audio to be unreliable. However, for non-techies it is a fairly complicated process to set an independent IP address.  It requires working through a series of re-configuration steps with a technician (your DSL provider) and it may not be necessary.  Many students have found that their systems work reasonably well with a Proxy IP address.  A common trick which allows students to use Netmeeting through a Proxy IP address is to lightly tap on their microphones whenever they lose audio.  Therefore, you may want to wait and see how your system works in the test sessions before taking the step of establishing your own IP address.

If you have trouble with DSL (whether wired or wireless), our server administrator (Mr. Hinrichs) recommends a specific set of port configurations for the maximum performance of your computer with Netmeeting.  The only wireless router which our system currently supports is the Linksys Wireless G router (available for about $60).   The main configurations for the router (whether wireless or wired) are contained in the following link: Linksys Router Port Settings

This set-up is for a single computer on the network running Netmeeting.  If you need to have multiple computers running Netmeeting, Mr. Hinrichs recommends that you obtain a separate external IP address for each computer. If you seek technical assistance Mr. Hinrichs is offering tech support service for $ 45 per incident.  His phone number is (760) 746-0980. Contact Mr. Callihan first by email ( if you wish to do this.

How do you know if you have a real external Internet IP?  Go to Start|Programs|Accessories|Command prompt and type ipconfig followed by ENTER.  If the IP address that you have begins with 192. or 172. you have a proxy address.  This address will not be the same as the external IP address that your computer actually has when connected to the Internet.  To see this IP address, go to  If your computer's IP address is not the same as your external address, Netmeeting may at times be confused and break your connection.  Usually you can quickly reconnect and return to the classroom.  However, if this becomes a chronic problem you may want to call your ISP and ask them to tell you how to reconfigure your system so that the external Internet IP address sits on the computer itself. 

1) Keep your windows machine updated at

2) Make sure you have some personal firewall and antivirus software running. For firewalls I recommend the excellent and free Zonealarm. For antivirus software, there is the standard Norton, but I recommend the free AVG.

3) Have and use antispyware software. I recommend three free programs: Ad-Aware, Spybot Search and Destroy, and Windows Defender.Run all three.

4) If you want to really work over the security of your windows machine, use this page. The recommendations are excellent and all of the programs recommended are free.

2. Using NetMeeting

1. Chat: There is a box near the bottom of the chat window that says "message". Click in this box and type what you want to say, then hit Enter and it will show up above in the chat window where everyone can see it. 

  2. Audio: In the middle of the main NetMeeting window (not the chat window), there are three buttons in a row; the third button has a picture of either a speaker and mic, or a face. Clicking this button will switch between these two pictures. If the speaker/mic is showing, then  underneath you'll see a list of all the people in the classroom. If the face shows, you'll see beneath it a microphone icon with a check box next to it. 

Check the box (by clicking in it) to turn your microphone on and talk, UNcheck it to turn your mic off. Always check to see that the mic box is UNchecked when you come into class, and never turn your mic on without permission from the tutor. Below this there is a speaker icon with a box next to it. This box should always be checked so you can hear. By both mic and speaker icons there are sliders that control volume. To increase the volume of what you send over your microphone or hear from your speakers, move the sliders to the right. To decrease volume, move them to the left.

3. To disconnect from the classroom,  a) first click the Hangup button on the main NetMeeting window (it has a picture of a telephone handset with an arrow pointing down);  then b) on the chat window, click File, then Exit;  then c) close the main window with the X in the upper right.

4. Other Important Notes:

1) WHITEBOARD OFF: Schola classes *never* use the whiteboard. Please be sure never to open it, and to always close it immediately if it opens.
2) MICROPHONE OFF: If you have a microphone, make sure that it is OFF by un-checking the box next to the microphone icon. See "Using NetMeeting, #2: audio.". Also, click on the small speaker icon on your start menu- usually at the bottom right of your screen.  Make sure that Mic is muted.  This well prevent feedback to your speakers.   3) To stop the irritating dings that occur when someone enters are leaves the conference, use the following procedure. 
  1. Start|Control Panel (or Start|Settings|Control Panel, could be different) 
2. Click "Sounds, Speech, and Audio Devices" (In the classic view, it is called Sounds and Audio Devices 
3. Pick the Sounds tab. 
4. Look in the box labeled "Program Events" and scroll to find NetMeeting. 
5. Click on each of the four items there and then click the drop down box, scroll to the top of the list in that box, and click [none]. 
6. Then click Apply and OK.

4) Video cameras cause NetMeeting trouble.  You do not need one for class, so if you have one it would be best to uninstall it. You can do this from your control panel. 

3. Troubleshooting NetMeeting if you don't hear audio (Note: After checking that you've done the above steps correctly, go through the below items carefully in order. For numbers 5-9 below, you may have to disconnect from the classroom before you make the changes.)

1. TAP ON THE MICROPHONE: Sometimes you can free up frozen audio by turning on your mic, tapping on the end of it two or three times, then turning it off again. If you have a router, sometimes it won't let the audio through and tapping on the mic will often solve this problem.  Usually no one hears the first tap, but will hear you after that.  Now you should be able to hear for the rest of the class, but if your audio stops, just repeat this procedure. If you don't have a mic, disconnect from the classroom and immediately reconnect and it may fix the problem.

2. SPEAKER ON: Make sure that your NetMeeting speaker is ON by checking the little box next to the speaker icon on the Netmeeting screen - i.e., there should be a check in the box. See "Using NetMeeting, #2: audio."

3. EXTERNAL SPEAKERS ON. If you have external speakers or a headset, make sure the speakers or headphones are turned on and the volume is turned up.

4. DISCONNECT AND RECONNECT: if you don't have a mic, or if tapping didn't do the trick, simply disconnect from the classroom and  reconnect again. This may bring your audio back.

5. SILENCE DETECTION: Here is a trick that can free up frozen audio.  Disconnect from the classroom. In NetMeeting, go to Tools | Options | Audio, then adjust the "silence detection" with the "manual" option ("Let me do it myself") - move the slider over to the far right.

6. TUNING WIZARD:  Disconnect from the classroom.  Run the Tuning Wizard in the main Netmeeting screen (Go to tools|options|audio). THEN make sure the full-duplexing is unchecked (tools|options|audio)

7. FULL-DUPLEX:  Disconnect from the classroom. Make sure the full-duplexing is unchecked (tools|options|audio)  Do this AFTER running the Tuning Wizard, since it will automatically turn it on.

8. BANDWIDTH SETTINGS:  Disconnect from the classroom.  28,800 or faster for 56K dial-up moderms.  There is a special setting to use for Cable/DSL/ISDN: go to Tools | Options | General | Bandwidth.

9. DISABLE "Compact" & "Data Only":  Disconnect from the classroom.  Go to the main NetMeeting window (not the chat box) and then select "View" and make sure "Compact" and "Data Only" are unchecked.

10. WHITEBOARD: Turn off the Whiteboard (click the "X" in the upper right corner of the Whiteboard window if it appears) whenever possible. Sometimes a second whiteboard will appear that cannot be closed right away.  Do not try to close this WB, but only minimize it.  After it finishes an initialization routine, then you can shut it.

11. CAMERA OFF: If you have a camera, turn it off.  Go to tools/options/video and disable (un-check) the "Automatically send video."  (The camera is a bandwidth "hog," and can really interfere with audio - we never use it.) 

12. 'PING' & 'DING' NOISE: To stop the irritating dings do the following.  1. Start|Control Panel (or Start|Settings|Control Panel, could be different) 2. Click "Sounds, Speech, and Audio Devices" (In the classic view, it is called Sounds and Audio Devices 3. In XP, under "Pick a Task", click "Change the Sound Scheme (again, in classic view, merely click the tab marked "sounds") 4. Scroll down in the list of sounds to NetMeeting 5. Anywhere you see a sound under NetMeeting (on my computer there are four), click the drag down box, scroll to the top of the list, and click [none].

13. DSL & CABLE: If you are on a network that uses proxy IP addresses instead of real internet IP addresses you may have to call your Broadband provider and ask how to configure your computer to use Netmeeting. But first see "Note to users of DSL and Cable modems" above. 

14. HOME NETWORKS: These regularly cause problems, but there are solutions. One that is a pain in the neck but that works is just to temporarily disconnect the rest of the home network and have only your NetMeeting computer on your DSL or cable box. For more indepth solutions to home network problems, I will refer you to Mr. Fritz Hinrichs, who owns and operates our NetMeeting servers, at

15. MISSING BUTTONS?: If the buttons don't show up in Netmeeting, that means it is not recognizing the sound card.  Check to verify the proper sound card. 

16. FIREWALLS can cause problems. If you're having audio trouble, try disabling the firewall if you can till class is over. You may have to disconnect from the internet, then reconnect after disabling the firewall. There is a built-in firewall in XP you can turn on and off--see Microsoft's firewall page.

17.  TEST YOUR SOUND CARD: If you still find that you are not able to get your audio to work with NetMeeting, you might have a problem in your mic or sound card.  The best way to trouble shoot your audio problems is to see if you can record and play back sound using the sound recorder.  You can find the recorder at Start | Programs | Accessories | Multimedia (or Entertainment) | Sound Recorder.  If you can not record and playback sound with the sound recorder, your problems are not with NetMeeting but your mic or soundcard.  Your mic should be in the "Mic in" hole on your sound card.

18. DISCONNECTED and CAN'T GET BACK IN? If you get disconnected from the classroom, often you won't be able to reconnect unless you shut down NetMeeting and restart it--you'll just keep getting messages saying the server won't answer. Sometimes you might need to disconnect from the internet, reconnect, then restart NetMeeting. Occasionally you'll need to completely reboot your computer--try it if the first two things don't work.

20. If after working carefully through the above (which speaks to the most common problems) you still do not have audio, you might read these suggestions and notes from various people who deal with these things:

a. A note from Mr. Hinrichs (the owner/operator of our NetMeeting servers and tutor at Escondido Tutorial Services) about highspeed connections, proxy IP addresses, and firewalls

b. Another from Dr. Lund, tutor at Oxford Classical Tutorials about the same thing

c. This letter is from a family describing their solution to a particular audio problem. It may or may not help you, but reading it might give you some ideas.

d. More questions and answers about proxy IPs, networking, ports, and firewalls.

e. Some people who could not get NetMeeting audio to work found they could run CU-SeeMe simultaneously with NetMeeting, using NM for chat and CU for sound. It's awkward but a possible solution. If you want to try this, download CU-SeeMe here and email me for a free registration code.

21. Last, if nothing else works, you can get tech support from Mr. Hinrichs (who runs our servers) and he will almost certainly be able to help you. But you must contact Mr. Callihan first ( There is a tech support fee ($45 per incident) which Mr. Hinrichs charges to me, and you must reimburse me for that.

4. Screen size and arrangement

You will almost always have your browser open as well as your CU-SeeMe window. In order to see both easily, first close any unnecessary programs and windows (leave the main NetMeeting window open). Leave the chat window and browser open. Then right click in a blank space on the task bar at the bottom of your screen, then left click "tile windows vertically". This will evenly distribute the browser and chat windows on your desktop. Alternatively, you can hover your cursor over the border of any window and drag it to the size you want. Click on the title bar at the top of any window to drag the whole window to a different location.

5. Getting your correct email address

Please make sure that you send me your correct email address. To make sure that your address is correct, simply send a message to yourself and see if it gets to its proper destination. If not, call your ISP to clarify your exact address.  Also, to make sure that you have your "Reply to" address correct, try replying to one of your own messages and see if it comes to you.

If you change email addresses, it is very important that you send me your new address immediately.

6. Copy and Paste

This is a very basic and necessary tool of computer use. You can copy text from any open application on your computer screen and paste it anywhere else.

a. Highlight the text you want to copy: drag your cursor over the text (hold down the left mouse button and while holding it down, drag it along the text until everything you want is highlighted, then release the mouse button). 

b. Copy the text: hold down the Control key and click the C button (Ctrl + C). Now the text is on your computer's clipboard. 

c. Paste it anywhere you like: clicking the left mouse button where you want to put the text, then hold down the Control key and click the V button (Ctrl + V).

7. Saving the class chatlog from NetMeeting
NetMeeting has a way of saving the chat - at the top of the chat window, under File, the Save As option will let you save the chat to your computer. DO NOT USE THIS. It will only save the most recent portion of the chat, and since Schola chat logs are so large it will not save the first portion of class.

Here is the way to save it all:

a. Click your cursor in the chatbox and hit Ctrl + A (this will highlight all the text).

b. Hit Ctrl + C (this will copy it all to your Windows clipboard).

c. Start a blank Word document, click the cursor in it and hit Ctrl + V (this will paste the chat into your document.

d. Save it wherever you like.

How to Establish NetMeeting Connections Through a Firewall

This information is helpful if you are using a cable modem or DSL line and are having trouble getting your audio to work.

The information in this article applies to:

Microsoft NetMeeting versions 2.0 , 2.1 , 2.11 , 3.01 , for Windows 95
Microsoft Windows 98
Microsoft Windows 98 Second Edition
Microsoft NetMeeting versions 2.1 , 2.11 , 3.01 , for Windows 98
Microsoft NetMeeting versions 2.1 , 2.11 , 3.01 , for Windows NT 4.0
Microsoft NetMeeting version 3.01 , for Windows 2000

This article describes how to use Microsoft NetMeeting to establish
connections over the Internet when you use a firewall to connect to the


When you use NetMeeting to establish a connection over the Internet,
NetMeeting uses several IP ports to communicate with other meeting
participants. If you use a firewall to connect to the Internet, the firewall
must be configured so that the ports used by NetMeeting are not blocked.
NetMeeting uses the following Internet Protocol (IP) ports:

Port Purpose
389 Internet Locator Server [Transmission Control Protocol (TCP)]
522 User Location Server (TCP)
1503 T.120 (TCP)
1720 H.323 call setup (TCP)
1731 Audio call control (TCP)
Dynamic H.323 call control (TCP)
Dynamic H.323 streaming [Realtime Transport Protocol (RTP) over User
Datagram Protocol (UDP)]
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

NOTE : Some firewalls are capable of passing through TCP connections on
specific ports, but are not capable of passing through secondary UDP
connections on dynamically assigned ports. When you establish NetMeeting
connections through these firewalls, you are unable to use the audio
features of NetMeeting.
In addition, some firewalls are capable of passing through TCP connections
on specific ports and secondary UDP connections on dynamically assigned
ports, but are not capable of virtualizing an arbitrary number of internal
IP addresses, or are not capable of doing so dynamically. With these
firewalls, you are able to establish NetMeeting connections from computers
inside the firewall to computers outside the firewall and you are able to
use the audio features of NetMeeting, but you are unable to establish
connections from computers outside the firewall to computers inside the firewall.

The H.323 call setup protocol (over port 1720) dynamically negotiates a TCP
port for use by the H.323 call control protocol. Also, both the audio call
control protocol (over port 1731) and the H.323 call setup protocol (over
port 1720) dynamically negotiate User Datagram Protocol (UDP) ports for use
by the H.323 streaming protocol, called the real time protocol (RTP). In
NetMeeting, two ports are determined on each side of the firewall for audio
and video streaming. These dynamically negotiated ports are selected
arbitrarily from all ports that can be assigned dynamically.
NetMeeting directory services require either port 389 or port 522, depending
on the type of server you are using. Internet Locator Servers (ILSs), which
support the lightweight directory access protocol (LDAP) for NetMeeting 2.0
or later, require port 389. User Location Servers (ULSs), developed for
NetMeeting 1.0, require port 522.
