Cannot Install Modem After Removing and Reinstalling
RAS
Symptoms:
After you remove and reinstall the remote access service (RAS) in Windows
NT 4.0, the Install New Modem Wizard may be unable to detect your modem.
Cause:
Removing and reinstalling RAS in Windows NT 4.0 causes the Modem.inf file
to be overwritten. Any changes or modifications made to the previous
Modem.inf file are lost.
NOTE: The Modem.inf file is not overwritten during the normal Setup
process. During Setup, the current versions of the Modem.inf, Switch.inf, and
Pad.inf files are not altered, and new versions of these files are saved as
Modem.new, Switch.new, and Pad.new.
Resolution:
If your modem is not on the Windows NT 4.0 Hardware Compatibility List
(HCL), use one of the following procedures to install your modem:
- Obtain an .inf file that is designed for Windows NT 4.0 from the modem
manufacturer. Follow the manufacturer's instructions for installing the
modem in Windows NT 4.0. Contact the modem manufacturer for assistance
with this procedure.
- Install your modem as a standard modem using the following steps:
- In Control Panel, double-click Modems.
- The Install New Modem Wizard starts automatically if you have not
installed a modem before. If the wizard does not start automatically, you
have installed a modem previously and you should click Add to start the
wizard.
- Click "Don't detect my modem; I will select it from a list," and then
click Next.
- In the Manufacturers box, click Standard Modem Types. In the Models
box, click a model that corresponds to the speed of your modem, and then
follow the instructions in the Install New Modem Wizard.
