Connecting to the Internet Windows NT 4.0 Dial-Up Networking (DUN)
Note: During the below steps, you may need to insert the Windows NT 4.0
STEP 1: Install Remote Access Services (RAS) (or verify it's installed)
Verifying that RAS is installed:
To find out if it is already installed, double-click My Computer, then
Control Panel. Double-click the Network icon, and select the Services tab.
You'll see a list of all of the networking services that are currently
installed on your system. Look for one labeled "Remote Access Service."
If you see that listed, then you can go on to Configuring Remote Access
Services. Otherwise, you need to continue to install Remote Access
Installing Remote Access Services (RAS):
You should be at the Network Services tab (My Computer/Control
Panel/Network). Click the Add button, and you'll be presented with the
Select Network Service window.
Scroll through the list of available services until you find one labeled
"Remote Access Service". Click on it to highlight it. Click the OK button,
and Windows NT will install that service. You'll be prompted for your
installation CD-ROM if RAS has not been previously loaded.
STEP 2: Configuring Remote Access Services (for Internet dial-in account)
Now that you have RAS installed, you need to configure it to use the
modem connected to your system. Highlight the Remote Access Service entry
on your Network/Services tab, and click Properties. You'll see a window
titled "Remote Access Setup", with no entries. Click the Add button. The
"Add RAS Device" window will appear.
Select the modem you want to use (most people only have one modem in
their system), then click the OK button. If you haven't previously
installed your modem, select the Install Modem button. You'll now
return to the "Remote Access Setup" window, and should see your modem
listed now. Click the Configure button, and you'll see the "Configure
By default, the Port Usage section will have "Receive Calls Only"
selected. Change this to the "Dial Out Only" option, or to "Dial Out and
Receive Calls" if you intend to also configure your system to receive
calls (not covered here). WARNING: Setting your computer to accept calls
can be dangerous if you don't set your security options correctly! You
could be making your system available to anyone with a modem and your
Click the OK button to continue, then click the Network button that's on
the right side of the "Remote Access Setup" window. You'll see a "Network
Configuration" window. Make sure that TCP/IP is the only protocol with a
checkmark. Click OK, then Continue to return to the Network/Services
window. Close that window by clicking OK. If Windows NT prompts you to
reboot, do so.
STEP 3: Create a Dial-Up Networking Connection
Now you're ready to get a connection set up, so you can get at the net
from your NT system! Double-click on My Computer and you should see an
icon for Dial-Up Networking. Double-click that icon. The first time you
create a DUN connection, Windows NT will beep and present you with a
dialog box saying "the phonebook is empty."
Click OK to continue. The "New Phonebook Entry" wizard will start, and
ask you to enter a name for the new phonebook entry. Type "WeirNet." Click
the Next button to continue. The next window of the Wizard asks for
information about the server you'll be calling.
Check the third option ("The non-Windows NT server...expects login
information...."), then click Next. The next window asks for the phone
number to your ISP. Enter the number (794-0300), then click Next.
You'll then be asked which protocol you need to use for connecting to your
ISP's computer. Select "PPP", then click the Next button.
You'll now see a window that allows you to select your login options.
Select "none," then click Next. You'll now be prompted for your IP
address. Leave the entry at all zeros. Click Next to continue.
Almost done! The wizard will now prompt you for your Domain Name Service
entries. Enter - DNS server: 220.127.116.11 WINS server: 0.0.0.0
You'll now see a window stating that you've completed the setup!
Congratulations! Now you can log on.
STEP 4: Logging On using your Dial-Up Networking Connection
Double-click on My Computer and you'll see an icon for Dial-Up Networking.
Double-click that icon. A window will appear with a drop-down box that has
all of your DUN connections listed (probably only one). Click the Dial
button to start the logon process.
A "Connect to" window will appear. Type your WeirNet assigned username
and password before clicking the OK button. Dial-Up Networking will then
dial the number for your ISP. You'll see a status box displaying
"Connecting to .... dialing...." and then "Connection Established."
You can now use any of your Winsock-compliant software, such as a web
browser, email programs, FTP software, etc.
After You've Connected:
Now that you've got your connection working and you've logged on, you'll
see a small icon in the taskbar notification tray. The top half of that
icon's background will turn blue during data transmissions, and the
bottom half will turn blue when data is being received.
You can double-click that icon to view the "Dial-Up Networking Monitor."
This window shows statistics for your current connection. You can also
click the Summary tab to see how long you've been logged on, and set some
options under the Preferences tab. When you're done using your connection
and want to log off, you can either click the Hang Up button on this
window, or single-click the DUN icon in the taskbar notification tray and
select Hang Up from the popup menu.
