Phonebook Entry Is Not Updated After Changing Modem

• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Workstation version 4.0

SYMPTOMS

After you change the modem in your Windows NT-based computer, you may experience one or more of the following problems:

• You can no longer connect to your Dial-Up Networking server or Internet service provider (ISP).
• You consistently connect at a lower speed than expected.

CAUSE

The Initial BPS setting in the modem configuration for Dial-Up Networking was not updated to reflect the settings for the new modem.

RESOLUTION

To resolve this issue, use the following steps to edit each phonebook entry:

1. Double-click My Computer, and then double-click Dial-Up Networking.

2. Click a phonebook entry in the Phonebook Entry To Dial box.

3. Click More, and then click Edit Entry And Modem Properties.

4. On the Basic tab, click Configure.

5. In the Initial Speed (bps) box, click the correct setting for your modem.

6. Repeat steps 2-5 for each phonebook entry.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

If your previous modem had a maximum speed that is slower than your current modem, your current modem will only connect at your previous modem's maximum speed. Or, if your previous modem had a maximum speed that is faster than your current modem, your current modem may not connect to the server at all.

NOTE: If you use a different COM port when you install a new modem, this issue does not occur.
