For example, we would use IPs: 208.38.4.101 => assigned as the router's public IP 208.38.4.102 => mail.mydomain.com 208.38.4.103 => ras2.mydomain.com ** doesn't like this ** 208.38.4.104 => www.mydomain.com 208.38.4.105 => ftp.mydomain.com Search for a recent change in any of the interfaces of the machine with troubles. I've updated the NIC driver with no success. If you're having a computer problem, ask on our forum for advice.

I don't really know why sometimes you managed to connect by method 2.

You may even encounter this error if the modem driver is not compatible with Windows XP.

This connection was working in the past.

Also, you need to make sure that the firewall permits the TCP traffic on port 1723. We'll let you know when a new response is added.

Everything works perfectly, EXCEPT PPTP (VPN) connections. It has been a while since I have had to use any of the netsh commands. I will share these findings with this forum in case others can benefit from our situation. I am not sure if I am clear on this?
