Error 721 dial-up connection wtih a modem

['Marieke]

I have w2k pro SP4 and i can't dial-in to my internet
provider. When I dial-up then he make conteact with the
server, then it is verivying my username and password and
then i get an error 721. I already checked with
servicedesk. And it looks like that my computer sends my
phoennumber as a password. But i for sure typed the
generated password in.
Can somebody help me to solve this problem? i am already
thinking about downgradgin to w98 se

Error 721: Remote PPP peer or computer is not responding. If you have tried
many thing other people suggest like rebooting, reloading hardware and
re-installing the VPN or dial in connection, you still get the same problem.
I will suggest to check the router settings and make sure TCP Port 1723, IP
Protocol 47 (GRE) are opened. Also make sure that the router has the PPTP
enabled and not firewall block the traffic. On the RAS server, check the
DHCP settings.
