CAUSE

The IBM MWave Modem is not initialized until the Mwmwin.exe file is executed. This file is executed when you log on to Windows NT 4.0.

Back to the top

Obtain updated MWave drivers from IBM.

As a workaround, log on to Windows NT using a local account, then log off. This will allow Windows NT to correctly use the Logon Using Dial-Up Networking option.
