Good guess IMO as this problem points directly to Win2000 only. I would not call this an Oracle proble, or think it likely that you will find answers in this forum.

FWIW, I have similar problems with Win2000 Pro on a desktop using PPP. WinME works fine. Linux works fine. On the _same_ machine, same modem, connecting to the same dialup server.

I would check two things - make sure that the PCMCIA modem and device driver work as it should, secondly make sure that the PPP settings are working as expected by runing repeated network tests on the notebook over PPP and see if that works (using Oracle for such tests is not a good idea as it is easier to test using ICMP and other protocols than SQL*Net/Net8).
