I just recently had this same problem with a new 56K V.92 modem. If I remember right I went to device manager and where it had the yellow question mark for PCI Device I highlighted it and uninstalled it. Then I restarted W2K and at the restart it found a New PCI Device and installed it and then the modem was recognized and I ran the driver disk that came with the modem. Works fine now. A modem wasn't even listed, just PCI devices with the yellow question mark.
Now, this may not work for you and I would surely wait for the more experienced guru's for an opinion before trying this. Mine was a trial and error type of thing. LG
