U need to configure network firewall to permit the GRE (Generic Routing Encapsulation) protocol 47 (if u use the same). We no longer have to retry up to 6 times to successfully connect. If you're having a computer problem, ask on our forum for advice. You would need to do a lot of tracing and sniffing to see what actually happens.

Both of these conditions are required in order to establish the virtual private network connectivity by using Point-to-Point Tunneling protocol. So then, I tried to run Remote Desktop from my laptop. No, create an account now. Error 721.

I get the error message: "Error 721: The remote computer did not respond." I created a new VPN connection icon, but still get the same results.

I'll send them an email and ask them. This explains how to force Remote Desktop traffic to use a different port, as the port 3389 is supposedly a target of hackers: http://www.dslwebserver.com/main/fr_index.html?/main/sbs-remote-desktop-change-port.html Then, I tried from work, and got Any insight into the VPN process would be helpful.
