I have a windows xp pro machine that had the modem stop working. Replaced modem and still wont work. I can query modem from the device manger modem properties but when I go to control panel and try to click on modem I get an error saying Phone and Modem control panel cannot be open. You may have a problem starting telephony service. I went to services and tried to start the service and I get an error 1084: This service cannot be started in safe mode. Can anybody shed some light on what this could be?
