IFR, two thoughts if you're still having difficulties and have not yet taken an axe to the beast.
1. Try using Hyperterminal to dial an ordinary 'phone number. (Programs>Accessories>Communications).
If you can dial out that way it would indicate that the modem is not the problem.
2. Go back to Device Manager and confirm which Port the modem is configured to use and then look at that Port and confirm that is is enabled.
Still thinking and reading...
The Trouble Shooter in XP is excellent and if you run it on the machine in question it will check various things for you such as resource conflicts. (Start>Help and support>Index>Dial-up networking>troubleshooter).
