We'll email youwhen relevant content isadded and updated. Following Follow Windows XP SP3 One machine is having a problem establishing a VPN connection with a remote server. It hangs on verifying the username and password. Another machine on the same network, using the credentials of the user who has the problem connects straight away. This has led me to believe that the problem is entirely with the one machine. I've updated the NIC driver with no success. I have created a new VPN connection but get the same results. I have even shut down the firewall on the local machine without gaining anything. This connection was working in the past.
