    Uninstall and reinstall, or uninstall, defragment, and reinstall.... but I would use a simple registry editor such as RegClean to also remove any peripheral files before the reinstall.

    Now, if the device is defective, which is sometimes the case, not much can be done except to replace the modem, or use a pcmcia modem
