I setup a VPN to my workplace using VISTA Ultimate 64 bit, but I am unable to set up a VPN on Windows 7 Ultimate, can any one suggest what I need to do?

So if you open the Network and Sharing Center then click on Setup a new connection or network then click on Connect to a workplace you can't create a VPN connection?MS-MVP Windows Desktop Experience, "When all else fails, read the instructions"

I have tried to delete the VPN and I was succesful, but when I set up the VPN, again it said that I could not connect to my work place. The first diagnostics stated that I could not connect on port 80 with aan error code of 807. Then I set up the VPN again, and I was told on the diagnostics that I could not connect on port 443 with an error code of 807.
