Can not RAS while Docked.

By bankslw ·
I've got a Latitude 650 with a 56k 3Com Modem (WinNT 4.0 Workstation). The problem is that while in a C/DockII docking station the modem does not detect a dial tone most of the time or states that there is no modem on the receiving end. I can RAS just fine while out of the station. I've uninstalled and reinstalled the modem drivers and the Remote Access Service with no success. I've also rebuilt the hardware profile. There are no errors in the eventviewer stating any conflicts. What would be the next step?...

Can not RAS while Docked.

The next step (if you haven't already)
would be support.dell.com to check for
updates to your model Lattitude.
Failing at that
Contact Dell and open a ticket with them.
Sounds like there is an incopatibility problem between docking station and laptop
while using this modem.

Have you tried different PCMCIA modems?
What about a serial Modem?
Same result with modem connected to serial
port on docking station? Then proceed to
contact Dell.
Problem goes away with serial modem?
Does problem also go away with another PCMCIA
modem? Yes? Change modems and notify Dell
of your discovery.
No? Contact Dell and open the ticket.

The BIOS was assigning an IRQ for the Docking Station that was causing a conflict with the modem. I changed the IRQ for the docking station and the modem is working fine now.
