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

CAUSE
=====

This issue may be caused by one or more of the following:

 - The transport protocol is disabled on the DOD interface

 - Your RRAS server is configured to use Dynamic Host Configuration Protocol
   (DHCP) to assign remote TCP/IP client addresses and the RRAS server cannot
   obtain addresses from the DHCP server.

   -or-

 - Service Pack 3 was reinstalled on the server, but Update on the Services tab
   of the Network tool in Control Panel was not run for the Routing and Remote
   Access Service.
