I noticed this same question was asked in March, but no answer.  Here it goes again.  I have been getting this message whenever i try to dial out with my modem.  There are no programs running and i shut everything down through the Cntl-Alt-Del end task screen.  I uninstalled-reinstalled the Dial Up Networking software from the win95 cd and reinstalled the modem.  Still the error still resides.  I tried changing com ports from com2 to com3, and upon the error, returned it to the original com2.   Any advice?????  Please..

Has it ever worked or is this just an intermittent problem?

It worked last week..  I made the mistake of adding RAM to my computer and after opening it up, installing the RAM, it started; so I took the RAM back out, thinking maybe for some reason that interupted something, but the error continues... everything else is functioning fine....

Is it possible that the internal modem has some option switches that got bumped in the installation?

I would also look for any loose wires that might have gotten bumped.  Some internal modems are plugged into a socket.  You may try to find the modem, pull it out, and "re-seat" it by plugging it back in.

I didn't notice any option switches, but I guess that is something to look for.  And when I re-installed the modem, i did pull it out and reseat it...

Can you test the modem in another PC?

Make absolute certain that no other programs are running. I get this message if my call anwering/fax software is running. Do a Ctrl+Alt+Del and click on "End Task" for everything except 'Explorer' and 'Systray'. Then try dialing out with your modem. If that works then reboot, and repeat the process, except try dialing out after ending task on each program until you find which one lets go of the modem. It's possible Windows could be loading some sort of fax software, that was previously installed, and it wouldn't show up on the task bar or in the tray.

Let me know if that helps...

Do you have another Device using the same Irq that the modem uses?

Hi, two things - First go to the control panel, then select the modem icon, select diagnostics, select the comm port and press the more info button. If the modem talks to the machine continue, if not then it appears your modem may have been moved by the plug and play feature and will need to be removed and then reinstalled.  If it does talk, try this to re-install dialup networking:

Go to control panel, select add/remove programs, go to windows setup tab, go to communications, select details, uncheck dialup networking. Reboot the machine. Then run INETWIZ from the run menu. This is the only way that windows will actually reinstall all the files to disk, otherwise it does a version check and leaves the other files on there...even if one is corrupt. If you get a message to replace a file because you have a newer one, you should let windows replace all files so you don't get a version mismatch. then after you get it working you could download the winsock2 etc and update. Good luck.

Thanx, your answer led me down the right path.  After seeing that the computer could not communicate properly with the port, I knew I needed to re-seat the modem.  I had to adjust motherboard to properly seat the modem.  Once that was done, it dialed up just fine.  I guess the problem existed between the chair and keyboard.... Thanx again.
