Question 1.2 I have intermittent disconnection problems; after connecting successfully and using the network, I am suddenly disconnected.
There are a number of possible causes for this; see Question 1.2 I have intermittent disconnection problems, in the Windows 95 connection FAQ.

Question 2.1 Error 629
You have been disconnected from the computer you are dialing.

• Error 629 is rather generic in that it does not indicate the cause of the disconnection. Most often it will appear in tandem with at least one other error message. If this is the case, identify the other error message(s) and troubleshoot from there.
• Otherwise, check configurations,check for possible causes of intermittent disconnection, and troubleshoot symptoms.
• If a solution cannot be discovered within UIC's troubleshooting guides, it may help to search other sources of information.

Question 2.2 Error 630
The computer is not receiving a response from the modem. Check that the modem is plugged in, and if necessary, turn the modem off, and then turn it back on.

Some possible causes for Error 630:

• There is a problem with the equipment (modem, cord, etc.).
• There may be an invalid command in the Extra Settings box in the Advanced Connection Settings window.
• There is a resource conflict, or a problem with the communications port settings.

• Verify or remove the string in the Extra Settings box.
  1. Click on Start, select Settings, then click on Control Panel.
  2. Double-click on the Modems icon.
  3. Under the General tab, click on your modem and then click on the Properties button.
  4. Click on the Connection tab.
  5. Click on the Advanced button.
  6. Make sure the Extra Settings box is empty, OR:
     If it is not empty, make sure the initialization string is correct.
  7. Keep clicking OK or Close until you return to Control Panel.
  
  
• Is there a problem with the communications port?
• Is there a resource conflict?
• Some problems can be remedied by removing the modem and adding it again. In the Control Panel double-click on Modems, select the modem, then click on Remove. Then restart the computer. If Windows 98 does not automatically detect the modem upon restarting, install it manually.
• If it still doesn't work, try removing and reinstalling all network components.

Question 2.3 Error 650
The computer you're dialing in to does not respond to a network request. Check your server type setting in the properties of the connection. If this problem persists, check with your network administrator.

• Error 650 is usually related to a problem at the Post-Dial TerminalScreen:
  • The Post-Dial Terminal Screen does not appear.
  • The dial-in ppp sequence was not properly entered in the post-dial terminal screen.
  • Stray characters appear in the post-dial terminal window, interfering with the login information while typing.

1. Double-click the My Computer icon on the desktop.
2. Double-click on Dialup Networking.
3. Right click on the icon for the number to be dialed.
4. Click on Properties.
5. Under the General tab, click on the Configure button.
6. Click on the Options tab.
7. Make sure there is a check in the box next to "Bring up terminal window after dialing". There should be no check before "Bring up terminal window before dialing".
8. Keep clicking OK until you return to Dial-up Networking.

1. Type your netid, then press enter.
2. Type your password, then press enter
3. Type "ppp", then press enter.
4. Click on the Continue button OR press the F7 key.
   • Note: You must not skip the step of pressing enter after typing "ppp"! This is one of the most common causes of dial-in failure.

1. Double-click the My Computer icon on the desktop.
2. Double-click on Dialup Networking.
3. Right click on the icon for the number to be dialed.
4. Click on Properties.
5. Under the General tab, click on the Configure button.
6. Click on the Connection tab.
7. Click on the Advanced button.
8. Make sure the box before "Use error control" is checked. Checking it will also place a check in the box before "Compress data"; this is okay.
9. Keep clicking OK until you return to Control Panel.

Question 2.4 Error 678
The computer you are dialing in to is not answering. Try again later.

Possible causes for error 678 include:

• The modem is dialing a wrong number.
• The Dialing Properties for the connection are set up incorrectly.
• The server is not answering because it is down or extremely busy, or connection attempts are timing out before completion.

• If the dialin server number is incorrect, follow the instructions for adding a new connection in Dial-up Networking.
• The icon for the incorrect connection number can be deleted by right-clicking on the icon and selecting "Delete".

1. I am in this country/region: -> United States of America.
2. Area code: -> your area code. Click on the Area Code Rules button to make sure no extra information has been entered.
3. To access an outside line: -> The boxes next to "For local calls" and "For long distance calls" should both be blank unless you are calling from a location which requires a special code for outside lines.
   Note: Dial-up Networking will automatically append a "1" at the beginning of any number for which the area code differs from that of the calling location; putting a "1" in the long distance box in this frame will cause duplication.
4. To disable call waiting, dial: -> If you have checked this box, make sure the dial code is correct for your telephone service and type of dial setting (tone or pulse). Check with your telephone company if you are unsure of the correct code. In most cases, call waiting will be disabled with "*70," for tone dialing and "1170," for pulse dialing, although this is not always the case. Don't forget the comma!
5. Dial using: -> Again, make sure you have selected the intended setting, whether Tone dial or Pulse dial, and that it is the correct type of dialing for the call waiting code you have entered above if you have selected the option to disable call waiting.
6. Dialing Properties settings not noted here are otherwise not relevant for local dial-in to UIC, but if you have additional configurations such as for a calling card number, make sure they are correctly typed. The Number to be dialed is displayed at the bottom of the window, exactly as the modem will dial it. If you are calling from area code 312, there will be an option to "Dial as a long distance call" below the number - this should not be checked.
7. Click OK.

• If increasing the S7 register does not help, the server may be down or extremely busy. Try connecting again later. Evening hours can be especially busy during mid-terms and the last couple weeks of a semester. You may have better luck connecting if you dial a different dialin line.
• If the connection hangs for a long time with the "Logging on to Network" message displayed before timing out, disable the "Log on to network" option.

Question 2.5 Error 680
There is no dial tone. Make sure your modem is connected to the phone line properly.

• This has to do with phone line usage and for the most part, the reasons are obvious - the same as for a telephone. If you have voice mail and are receiving a stutter dial tone to announce messages, you will also get this error, but there is a work-around in case you do not want to check the voice mail messages immediately:

1. Open Dial-up Networking and double-click on the icon for the phone number to be dialed.
2. Click on the Dial Properties button.
3. In the box following "To disable call waiting, dial:", type commas in front of the disable code. If disabling call waiting is not desired, then check the preceding box as if to disable call waiting but, instead of a disable code in the following box, type commas only. This tells the modem to pause before dialing. Start with 2 commas and increase if a longer pause is needed.
4. Click OK.

Question 2.6 Error 720
The Microsoft Dial-Up Adapter is not configured to work with the current network configuration. Please check your server type and the network configuration in the Control Panel then try the connection again.
- OR -
Dial-Up Networking could not negotiate a compatible set of network protocols you specified in the Server Type settings. Check your network configuration in the Control Panel then try the connection again.

• The Server Types settings in Dial-up Networking may be incorrect, even if the TCP/IP configurations in the Network components of the Control Panel have been checked for accuracy.

1. Click on the Start button, then select and click on Programs -> Accessories -> Communications -> Dial-up Networking.
2. Right-click on the icon for your UIC connection.
3. Select and click on Properties.
4. Click on the Server Types tab.
5. The selection under Type of Dial-up Server should be "PPP: Internet, Windows NT Server, Windows 98".
6. The boxes preceding "Enable software compression" and "TCP/IP" must be checked.
7. After correcting or verifying these settings, click OK.
8. If this does not correct the problem, check for errors with the network components or PPP configuration.

Question 3.1 Where can I find configuration information?

• Configuring Win9X PPP for Modem Use:
  http://www.uic.edu/depts/accc/network/dialin/win95.ppp.html
  (Follow configuration for Win95 or Win9X when Win98 is not specified.)

Question 3.2 When I try to connect my computer displays the message "Logging on to network..." and hangs for a long time before finally connecting or timing out.
When the Log on to network option is selected, the Dial-Up Networking service tries to find a Microsoft Windows network.

Resolution: Disable the Log on to network option:

1. Click on Start, point to Programs, point to Accessories, point to Communications, and then click Dial-Up Networking.
2. In the Dial-Up Networking dialog box, right-click the icon for the UIC dial-in connection, and then click Properties.
3. Click on the Server Types tab.
4. Click in the Log on to network check box to clear it.
5. Click OK.

Question 3.3 I checked and re-checked my configuration. I checked the Troubleshooting Guide. It still doesn't work. What is there left to do?

• Go into the Network Control panel, and remove EVERYTHING. Then shut down the PC, turn it all the way off for at least 10 seconds. Restart it and re-add the components, then re-start again. This often works, we don't know why, but it does.
• If you're still stuck, contact your modem manufacturer or Microsoft.
