I have a laptop that wont connect using VPN it used to work fine and then when It was connected to another network for the day it stopped working. It is able to connect to the internet and networks ect and It is not using Dial up or a Modem. I have tried to connect a few times now and It still gives the same error. However other laptops can connect to the same VPN. I have also tried connecting with the firewall disabled so it is not a firewall fault. The Laptop is running Win 7 X64.
