Hello,

I am getting an error on all D600 machines that we have running Windows 2000 Pro with SP3 applied.  The error I get is error 721, Remote PPP peer is not responding.  If I remove DUN and reinstall I then get an error 657: The device .INF file could not be opened when I click on either the Configure button or on the Security tab from within dial up networking.  I have uninstalled/reinstalled the modem, dial up networking, reinstalled the chipset drivers and spent several hours with Dell Technical Support.  All to no avail.  The modem in the machines is the Conexant D480 MDC V.92 Modem.

Any Ideas???
