Question 1.1 I am trying to configure Windows 95 to work with the UIC dialin lines but it isn't working. Where can I find configuration information?

• First, double-check to make sure you have set everything correctly according to Instructions for configuring PPP for Windows 95. (or see the configuration for Windows NT )

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:

• Time Limit
  All UIC Dialin lines have a 5 hour time limit. If you were connected for 5 hours, your connection is automatically terminated at that time.
• Idle Time
  All UIC Dialin lines have a 25 minutes idle time detector. If you do not use your connection for 25 minutes, you will be automatically terminated.
• Call Waiting
  If you have Call Waiting on your telephone line, it can interrupt your connection and terminate it. You can disable it by adding *70, to the beginning of the phone number you are dialing.
• Multiple Telephones
  If you have multiple telephones in your house, a connection may terminate if another telephone is picked up by mistake.
• Only at this Speed. . .
  For Windows 95, right-click on our Dialin connection, then click on Properties, then click on Configure, then be sure that the box Connect Only at this Speed is NOT checked.
• Line Noise
  Telephone line noise, caused by interference or old/failing wires, can slow down your connection speed and can often disconnect you if the noise is bad enough. You can have your phone company check your lines if you suspect problems.
• Hardware
  A number of other possibilities exist. Your modem might be faulty, or other hardware. Or, you might have a virus, or there might be corrupted files on which the connection is dependent. In addition, the problem might be caused by the UIC Dialin server. If your modem seems to be working fine with other connections, or you suspect the problem is with our dialin servers, please notify our Network Operations Desk, which is available 24 hours a day.

Question 2.1 A required .DLL file, WSOCK32.DLL, was not found.

• Windows 95 could not find WSOCK32.DLL, there is more than one copy of WSOCK32.DLL, or WSOCK32.DLL is corrupt.

Resolution

1. Go to the Start button
2. Click on Find
3. Click on Files or Folders
4. Type in wsock32.dll in the Named: field
5. If you find wsock32.dll and it is 65KB, move it to the Windows/System folder.
6. If you don't find it or it is not 65KB, you will need to get a copy of wsock32.dll from another computer.
7. If you find more than one copy of wsock32.dll, delete one of them and put the wsock32.dll file that is 65KB in the Windows/System folder.

Question 2.2 Verifying user name and password , and it never goes away and it never connects.

• You may have entered the dialin sequence (netid, password, ppp, continue) incorrectly.
  • Please make sure that you have entered your netid, then enter, your password, then enter, ppp, then enter, then continue (or F7).
• They do not have "Bring up terminal window after dialing" in the connection properties. By default, the first connection icon that you make will have "Bring up terminal window after dialing", but the rest will not.

Resolution

1. Go to My Computer
2. Double-click on Dial-up networking
3. Right-click on the UIC dialin icon
4. Select properties
5. Click on the Configure button
6. Choose the Options tab

• Also, make sure there is a check in the "Bring up terminal window after dialing". There should be no check before "Bring up terminal window before dialing".

Question 2.3 The computer is not receiving a response from the modem.

• This behavior can occur if you have an invalid command in the Extra Settings box in the Advanced Connection Settings dialog box.

Resolution

Verify or remove the setting in the Extra Settings box. To do so, follow these steps:

1. In Control Panel, double-click Modems.
2. On the General tab, click your modem and then click Properties.
3. On the Connection tab, click Advanced.
4. Make sure the Extra Settings box is empty.
5. If it is not empty, make sure the initialization string is correct.
6. Click OK or Close until you return to Control Panel.

Question 2.4 Dial-up networking could not negotiate a compatible set of network protocols.

This error message can be caused by any of the following situations:

• You may have entered the dialin sequence (netid, password, ppp, continue) incorrectly.
  • Please make sure that you have entered your netid, then enter, your password, then enter, ppp, then enter, then continue (or F7).
• The network protocols used by the server do not match the protocols used by the Dial-Up Networking client.
• The protocol used by the Dial-Up Networking client is not available.
• The line protocols may not match.
• You may be using a PAP or CHAP login and a clear-text terminal login is needed. PAP and CHAP authentication use the user name and password you type in the Connect To dialog box when you dial. A terminal login occurs after modem negotiation.

Resolution

Check your PPP configuration. If that doesn't work, check these:

1. Go to Start, Settings, Control Panel, Network
2. Double-click on TCP/IP
3. Go to the WINS Configuration tab
4. Make sure it is marked as Disable WINS and there is nothing checked inside that panel.

You did not configure the dialin connection icon correctly:

1. Go to My Computer
2. Double-click on Dial-up networking
3. Right-click on the UIC dialin icon
4. Select properties
5. Click on the Configure button
6. Choose the Options tab
7. Make sure there is a check in the "Bring up terminal window after dialing". There should be no check before "Bring up terminal window before dialing".
8. Click OK at the bottom of the modem properties window
9. Click on the Server Type button and make sure the appropriate boxes are checked:

• Don't check these:
• Log on to network
• IPX/SPX Compatible
• NetBEUI
• Check TCP/IP (very, very important)
• The other options shouldn't matter

If a protocol used by the Dial-Up Networking client is not available, install the protocol from Control Panel and bind it to the Dial-Up Networking adapter.

Check if the driver for the modem is proprietary. Remove and install the "Standard" driver:

1. First, delete the current modem:
   • From the Start Menu, go to Settings, Control Panel, System
   • Click on the Device Manager tab, then click on the + next to "Modem"
   • Highlight the proprietary modem, and select "Remove"
   • Click on "OK" until the modem is removed
2. Cold boot the machine by shutting in down completely. Then turn the computer on.
3. Reinstall the modem with the "Standard" driver:
   • If Windows 95 does not detect the new hardware during boot-up, follow this procedure:
     • From the Start Menu, go to Settings, Control Panel, Add New Hardware
     • Follow the instructions and have the computer detect the new hardware
     • When asked what type of modem is installed, choose "Standard", and the speed of the modem
     • Complete the installation
   • Windows 95 may detect the modem while the machine boots up if it is "plug and play", and install the "Standard" driver automatically.
4. Reboot your machine after the installation, then try dialing in again.

Question 2.5 The Pre-Dial Terminal Screen appears.

• This means that you did not tell Dial-up Networking that you would like a terminal login. Chances are, you did not check "Bring up terminal window after dialing" in the connection properties

Resolution

1. Click on Start, Programs, Accessories, Dial-up Networking
2. Right-Click on the UIC-1 icon
3. Choose Properties
4. Click on the Configure button
5. Choose the Options tab
6. Make sure there is a check in the "Bring up terminal window after dialing" there should be no check before "Bring up terminal window before dialing".

Question 2.6 Unable to resolve host address or unable to locate the server.

• If you are off campus, this might be caused by having an IP address specified in the TCP/IP settings in Network control panel.
• Not having the correct DNS entries in the TCP/IP settings.
• Having more than one TCP/IP listing in the Network Component window.

Resolution

1. Go to Start, Settings, Control Panel
2. Double-click on Network
3. Double-click on TCP/IP
4. Click on the IP Address tab
5. Check "Obtain an IP address automatically"

1. Go to Start, Settings, Control Panel
2. Double-click on Network
3. If you have TCP/IP listed more than once in the component window:
1. Double-click on TCP/IP
2. Check a couple of things from the Configuring PPP document to see if it is configured properly.
3. If it is configured properly, click OK and delete the other TCP/IP listing in the network components window.
4. If it is not configured properly, click OK and delete that TCP/IP listing. Then you will have to go into the other TCP/IP listing and configure it from the Configuring PPP document.

1. Go to Start, Settings, Control Panel
2. Double-click on Network
3. Double-click on TCP/IP
4. Click on the DNS Configuration tab
5. Make sure at least two of these three numbers are listed under DNS Server Search Order:
   • 128.248.171.50
   • 128.248.2.50
   • 128.248.7.50

Question 2.7 Problems opening the Dial-Up Networking folder

• This behavior can occur if the Rnaui.dll or Msvcrt20.dll file in the Windows\System folder is missing or damaged.

• To resolve this problem, rename the Rnaui.dll and Msvcrt20.dll files in the Windows\System folder (if the files exist), and then extract a new copy of the Rnaui.dll and Msvcrt20.dll files from your original Windows 95 disks or CD-ROM.

Question 2.8 Tapi Error

• The driver it names may be using the same IRQ as the modem.

Resolution

1. Click the Start button, point to Settings, then click Control Panel.
2. Double-Click on the Display icon
3. Click on the Settings tab
4. Click on the Advanced Properties button
5. Click on the Performance tab
6. Move the Hardware acceleration switch to None

Question 2.9 You must specify your workgroup to the Network

• The Workgroup field is blank under Start/Settings/Control Panel/Network/Identification.

Resolution

1. Go to Start, Settings, Control Panel
2. Double-click on Network
3. Click on the Identification tab at the top of the screen
4. Fill out the Workgroup: field with whatever you want (most people use their department)
5. Click OK at the bottom of the screen to save the changes

Question 3.1 When dialing, I hear a carrier tone; but, after 15 or 30 seconds, I'm disconnected.

• The S7 register, which controls the amount of time the modem waits for a carrier, probably does not have a sufficient value for the modem to recognize a compatible carrier issued by the remote modem.

Resolution

Set the S7 register to a value of at least 60. To do so, follow these steps:

1. Click the Start button, point to Settings, then click Control Panel.
2. Double-click the Modems icon.
3. Click Properties.
4. Click the Connection tab.
5. Click the "Cancel the call if not connected within" check box to select it, then type "60" (without quotation marks) in the Secs box.
6. Click OK or Close until you return to Control Panel.

Question 3.2 I still can't figure out the problem. How can I make a log of the connection so that I can trace the problem?

• If none of these suggestions work, it could be very helpful to create a ppplog. You can use the Ppplog.txt file to troubleshoot problems using the PPP line protocol with the Microsoft dial-up adapter. The file contains a detailed listing of the steps that occur during a remote access connection using PPP.

Resolution

To create a Ppplog.txt file, follow these steps:

1. In Control Panel, double-click the Network icon.
2. Click Dial-Up Adapter, and then click Properties.
3. Click the Advanced tab.
4. In the Property box, click Record A Log File.
5. In the Value box, click Yes.
6. Click OK until you return to Control Panel.

• The next time you attempt a PPP connection, the Ppplog.txt file is created. The file is located in the Windows folder and can be edited using any text editor or word processor. If the file already exists, new information is appended to it.

• NOTE: If you do not use the Ppplog.txt file for troubleshooting problems you should disable its creation, because the file can become quite large after you make several connections.
• If all else fails, delete all of the network components (Dial-up Adapter, TCP/IP, ...) and reinstall both. When this is finished, check all the TCP/IP settings and reboot.

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.
