I formatted a HDD then installed Win 2000 Pro. Everything works fine except that the internal modem doesn't get detected. I tried the Add/Remove hardware wizard and the modem 'self-test' which said that the device failed to communicate. The modem worked fine when Windows ME was installed. I've also opened up the case to make sure that the modem was seated correctly. I checked the Hardware compatability List which the modem was missing. Does this mean it won't work at all with W2K Pro? The modem is a Packard Bell V.90 Data Fax Modem (56kbps).
