DUN ERROR 651

Your modem (or other connecting device) has reported an error.

  1. If the modem is not dialing and trying to establish a connection then check to make sure that the modem is installed properly and responds to diagnostics.

  2. Make sure that no other programs are using your modem. Fax software, Supervoice, etc...

  3. Ctrl-Alt-Delete, if you see RNAAPP loaded, then double-click it to close the program.

  4. If the modem is dialing and trying to establish a connection then try modem driver updates/init strings after checking all of the user's settings.

  5. Do a full internet (DUN, Network, dialers, pwl's, etc..) uninstall and reinstall.
