I have Xp operating system have primary dos and Xp installed in the extended portion. I installed windows Xp first then I installed the driver from creative labs for the 56K modem, when it dials the phone number and connects to the internet it works ok, but if you lose or diconnect your connection to the internet and it starts to attempt to redial you get the message error no dial tone over and over, but if you shutdown the computer and reboot then dial it will work. I have a 10/100 network card not connected and the modem is in an isa slot the driver for modem is for windows Xp and I already have uninstalled and reinstalled. I reset winsock.  Where do you look to fix this problem?
Have you tried taking out that 10/100 network card?

SOMETIMES a modem and a network card have a
conflict...........I would also uninstall it from device
 manager ,or choose 'Do not use this device(disable).That MIGHT work will not be able to hook two computers together could use usb ports though. Maybe uninstalling network card might work, hope you don't need a driver for network card as I don't have one. Quote
