When you create a Dial-Up Networking connection, the icon that you’ll see in Dial-Up Networking in My Computer represents the connection profile you’ve created. This profile (information stored in the system registry) is known as a Dial-Up Networking Connectoid. (I wonder who makes up these words?)
Creating the DUN Connectoid
Double-click the My Computer icon on the Desktop and then double-click Dial-Up Networking. Double-click Make New Connection to launch the wizard. In the name field, type a name for your connection, usually the name of your Internet provider, call it whatever you want. In the Select a Device field, choose your modem from the drop down list. (Note: If Windows does not know about your modem yet and has not detected it yet, it will at this point prompt you to install it.) Click the Next button and enter the area code and phone number of the computer you will be dialing. After entering the number and choosing a country code from the drop down list, click the Finish button and the connectoid will be created.
Configuring the Connectoid
Now the fun begins. It is time to enter some of that info that you received from your ISP. Right-click on your new connectoid in Dial-Up Networking and choose Properties. On the General tab, you will see the telephone number that you entered. Uncheck the box Use Area Code and Dialing Properties (unless you are going to be dialing long distance where a country code is needed). You will see the area code and country code fields grayed out. Now is the time to edit the field with the telephone number, if you need to dial an area code for a local call simply enter it in the telephone number field itself. If you have call waiting you should disable it here as well. Enter the appropriate code before the phone number. For example, *70 in my locality. Look at the little booklet that came with your phone to see what codes to use to disable extra features. Here is an example of what the telephone number field should contain (if you have call waiting and need to dial an area code for local calls)
*70 to disable call waiting, a comma for a short pause, then the ten digit local number – hyphens not needed
You can also configure your modem for the connection from here. Click the Configure Modem button and you can select which COM port it’s going to use. The modem should already be configured at this point, but the settings are there. When finished with the General tab, click the Server Types tab. The type of connection should be Windows PPP (by default that’s what will be selected). Your ISP should have told you on the telephone if it is to be anything different. Uncheck Log onto Network (unless your ISP said otherwise when you asked) and check Enable Software Compression. If your ISP doesn’t support that, checking that box won’t affect anything (most all do though). In most cases, that is the only box you need checked in that section. Now, below that in the Allowed Protocols section, chances are the only protocol you should allow is TCP/IP, unless you plan on NetBEUI fileshares or perhaps IPX/SPX Internet Gaming. (That protocol is normally used for Novell Netware networking, but some internet games use that protocol…in which case you’d have to have it installed in Network in Control Panel).
Now, the next thing to do is still under the Server Types tab; click the TCP/IP Settings button. Select Server Assigned IP Address unless you have been told otherwise. This means that every time you connect to the ISP, they will assign you an IP address for that online session. Once you hang up, they’ll re-use it because you have no use for the IP while off-line and there are only so many IP addresses. And the next time you log on, you’ll get another one. This is called Dynamic IP.
A static IP would be if your ISP assigns you one IP when you sign up and you get to keep it for as long as you are subscribed to their service. This is usually only the case when you have a type of Internet service that has you connected 24/7, like a cable modem or DSL. And if you have one of those, then you don’t need Dial-Up Networking because you’re connected all the time and probably wouldn’t be reading this tutorial.
Next, your ISP should have provided you with the Primary and Secondary DNS when you asked them. If not, select Server Assigned Name Server Addresses. Otherwise select Specified Name Server Addresses and enter the values given in the fields. Leave the WINS fields blank, they are for a different type of address resolution; a Dial-Up service provider isn’t likely to use WINS. Leave the two boxes Use IP Header Compression and Use Default Gateway on Remote Network (important!) checked unless otherwise told. You’d have to enter gateway addresses in TCP/IP properties in Network in Control Panel otherwise…and you’d have been instructed accordingly.
