Error 721

[Guest]

I was out of town working remotely via VPN. As always on many different sites
I will VPN for email, look at files on my SBS2003 server. I have a Verizon
Internet card and normal wirless as well as hard connection. When i came
home, I cannot get on to my VPN connection.

I can telnet port 1723, RWW and RDP into the server.
I can go onto other computers (that are not on my site) and VPN just fine.
I have reset the login and password on the account.
Tried the Verizon connection, which has never failed me.
Tried creating new VPN account.

Any ideas?

Assuming you can telnet port 1723, it could be GRE issue.Try to troubleshoot
it using PPTPclnt and PPTPsrv tools. This link may help,

and TRACERT to check the connection ...
