Configuring PPP Dialup on a Windows PC

Overview

Three things are necessary to use PPP:

1. a fast modem (14.4 kbps is the practical minimum),
2. a TCP/IP driver, which is a piece of software that lets the computer speak the standard Internet language, and
3. a PPP driver, which takes that Internet language and pumps it into the modem pipeline.

Setting up PPP Dial-Up Networking under Windows 3.1

Under Windows 3.1 you need to obtain a shareware package called "Trumpet Winsock", or an equivalent commercial package. Follow the instructions that came with it, using the following data:

phone number to dial: 753 6600
IP address: leave blank, or choose "dynamically assigned"
gateway or router address: 0.0.0.0
DNS (domain name server): 131.156.1.11 (and 131.156.3.3, if there is space for a second one)
domain name: niu.edu
POP and SMTP hosts: mail.math.niu.edu in both fields
Ph server: corn.cso.niu.edu

Setting up PPP Dial-Up Networking under Windows 95
(purloined from Netscape's Web site)

Windows 95 includes the necessary PPP and TCP/IP drivers.

Step 1: Before proceeding with configuration, make sure you don't have multiple WINSOCK.DLLs. Follow these steps:

1. Click Start
2. Click Find
3. Select Files or Folders
4. Type WINSOCK.DLL in the Named Box
5. Make sure Look In is set to C:\
6. Click Find Now

Note: If you have more than one local drive (such as D:\, E:\ and so on), repeat the above procedure for each drive.

Step 2: Make sure Dial-Up Networking is installed

1. Click Start
2. Select Settings
3. Select Control Panel
4. Double-click the Add/Remove Programs Icon
5. Select the Windows Setup Tab
6. Single-click Communications, then press the Details button
7. The Dial-Up Networking item should be checked. If it isn't, check it

Note: The following steps assume you already have the Dial-Up Networking installed.

Step 3: Make sure the Client for Microsoft Networks, Dial-Up Adapter, and TCP/IP Protocol are installed

1. 1.Click Start
2. 2.Select Settings
3. 3.Select Control Panel
4. 4.Double-click the Network Icon
5. 5.Verify that Client for Microsoft Networks is listed. If it isn't:
   • Click Add
   • Double click Client
   • Select Microsoft
   • Select Client for Microsoft Networks
   • Select OK
     You may be prompted for your Windows95 Disks or CD-ROM. Provide the disk and click OK.
6. Verify the Dial-Up Adapter is present.
   If it isn't
   • Click Add
   • Double-Click Adapter
   • Scroll down the list and select Microsoft
   • Choose the Dial-Up Adapter and click OK
   • You may be prompted for your Windows95 Disks or CD-ROM. Provide the disk and click OK.
7. Verify the TCP/IP Protocol is present.
   If it isn't
   • Click Add
   • Double-Click Protocol
   • Scroll down the list and select Microsoft
   • Choose TCP/IP and click OK
   • You may be prompted for your Windows95 Disks or CD-ROM. Provide the disk and click OK.
8. Click OK until you are asked to restart the system. After you restart, proceed to the next step

Step 4: Setting up the connection

1. Double-click the My Computer Icon
2. Double-click the Dial-Up Networking Icon.
3. If you already have one Dial-Up connection, just click on New Connection icon. If you never run DIal-up networking before, you will see Dial-Up networking wizard. Type in the name of your provider for the name of the computer you want to connect to, for example, "NIU connection" or just "NIU"
4. In the following step, your modem should already be displayed. If it isn't, consult your Windows95 documentation for information on how to set up your modem for use with Windows95
5. Click Next>
6. Type in the phone number (currently 753 6600)
7. Click Next>, then Finish
8. Single-click the newly created dial-up icon with the RIGHT mouse button, and select Properties
9. In the Phone Number section, make sure the Use Country Code and Area Code option is checked and you have entered your area code. This is necessary if you want to use the Disable Call Waiting option. However, if the dialup phone number has a different area code than you but it is still a local call, you will have to unselect the Use Country Code and Area Code box and enter your number preceded by the area code and call waiting disabling sequence into the phone pumber box, for example, *70,(123) 234-4567. This will allow you to disable call waiting AND dial without a "1" in front of the area code.
10. Click the Server Type Button
11. The Type of Dial-Up Server should be set to PPP: Windows95, WindowsNT 3.5, Internet
12. In the Advanced Options Section, make sure that:
    • Enable Software Compression IS Checked
    • Log On to Network IS Checked
    • Require Encrypted Password IS NOT Checked
    • TCP/IP should be the only protocol enabled. Disable IPX and NetBUEI
13. Click on TCP/IP Settings
14. Make sure Server Assigned IP Address is selected.
15. Make sure Specify Name Server Addresses is selected
16. Put in the following DNS Server IP Addresses provided by your ISP: 131.156.1.11, 131.156.3.3
17. For the Primary and Secondary WINS configuration, leave them at 0.0.0.0
18. Use IP Header Compression should be Checked
19. Use Default Gateway on Remote Network should be Checked
20. Click OK twice

Final Step: Connecting!

Double-click on the new provider Icon. You will be prompted for the username and password which ACS assigned to you.

Depending on what account you received, the tail end of your username will be different. For example, if the paperwork you received from ACS says the account tf0hst1 is on "corn", you should use the string tf0hst1@corn.cso.niu.edu as the username at this point. See this document for more details.

Keep in mind that the password is case-sensitive.

Troubleshooting:

1. If you are having problems saving password, check out article 960613-4 in our Knowledge base: "Correcting the greyed-out password option".

2. Some people have reported getting an Unable to negotiate compatible dial-up protocol error message. We have found that putting in a host and domain name in the TCP/IP Properties in the Network section of Control Panel seems to correct the problem. If you run into this error, we recommend trying this to resolve the problem.
