Aspen

I have a Dell desktop computer. About 6 months ago, when I would try to connect to the internet (dial-up) a message would pop-up saying, "port open..modem in use by another program or not configured correctly." I cannot see any problem on the device manager//the modem is enabled//when I quiery the modem, port 1 show no modem and port 3, where3 the modem is supposed to be just displays for a moment and then the test is over.

Any thoughts?

thanks a lot
