Restart the computer as Microsoft recommends. If this doesn't help,
check if your modem is responding: go to Control Pannel -> Modems ->
Diagnostics, select the COM port your modem is located on, Click on
"More info". If modem responds, highlight the modem, remove it and restart
the computer. Reinstall the modem. If you still getting the problem,
disable RNAAPP: press Ctrl+Alt+Del, highlight RNAAPP, click on "End task"
and reboot your computer.
