3. Check the circle next to Restart and click OK.
4. If you have an external modem, turn its power off then on. If there is no on/off switch on the modem, you may have to unplug the modem's power supply.

Configuring the Windows Network Components for Dial-Up-Networking

The following instructions are for those systems that are not on a Local Area Network (LAN). If you are on a LAN and follow these directions, you may create a conflict that will disrupt your computer's connection to your LAN. Please contact your network administrator for assistance before you continue making any changes to the system configuration.

1. Click on the Windows Start button, point to Settings and select Control Panel.

2. Double-click the Network icon.
   
   IMPORTANT!
   Before making any changes to your Network settings, please ensure that you have your Windows CD.

3. Click on the Add button.

4. Under Manufacturers, select Microsoft.

   Note: This may automatically add all three components.

If Dial-Up Adapter is not listed, you will need to add it:

1. Click on the Add button.

2. Select Adapter.
3. Click on the Add button.
