One time... when having a problem with loading the modem. I had to remove
the Network Adaptor and Modem from the Device manager list and reboot. Then
reinstall the Network Adaptor. Once I did that the system instantly saw the
modem and asked for it's drivers. And everything worked.
Have no idea if this will help you. Just a suggestion from my past
experiences.

cannot get dun to work with aztech mdp3880-w(u) modem.

installed latest drivers, install went fine. "more info" reported info
from the modem.

When I try to dialout using dun i get : "error 633- modem is not
installed or configured for dialup, double click on the modems icon in
control panel"

When I do the above, it tries to reinstall the modem drivers,even though
they have already been installed.

Tried on of MS's solutions and rebuilt telephon.ini, still no go. Also
did their registry fix for telephon.ini

tried uninstalling and reinstalling drivers and modem still no problem.
Modem now assigned to com3 IRQ 10

in my Dell dimension bios, there is a section for all the irqs where u
set it to either available or reserved, but I was told that this is only
for non-plug and pray modems and I got a message from windows saying
this is plug and pray modem. IRQ is currently marked available in bios.
