More about Error 721
Error 721 generally means that there is a problem with the remote PPP - the PPP
server resides with the Internet / broadband provider and is the computer at
'the other end of the line' that establishes connections to the Internet. The
majority of Error 721 messages are caused by a 'problem' with the Internet
service provider. Most Internet service providers have a number that can be
called to check their service status. With Error 721 problems, it is therefore
worth checking the ISP's service status before checking other possible
causes.
Another possible cause of Error 721 messages can be displaced
modem connections, adsl cables and / or broadband filters. If an Error 721
message has not been caused by the ISP, it would be prudent to check all such
connections. Common advice is then to shut down both modem and PC and to wait
5-10 minutes before restarting them. Wait until all PC application have fully
loaded before attempting to reconnect to the Internet.
Where there are
no ISP service issues and all modems, filters, cables are correctly connected -
another possible Error 721 fix would be to check all associated PC settings and
to update / uninstall modem drivers, reboot and reinstall them again and whilst
doing so - take care not to connect the modem until prompted to do so by the
setup program.
Where no fix is found for Error 721, if time allows -
wait 24 hours and try again or seek either local or ISP technical support. You
might also be advised to google for error 721 as there is a wealth of
information available via the various forums and blogs.
