    OK...as a test I connected to this free PPTP VPN service to make sure my iPod Touch VPN functionality would work.

    http://www.bestfreevpn.com/iphone-ipad-free-vpn/

    After configuring the server settings I was able to successfully connect, verify my iPod Touch IP had changed to the IP assigned by their PPTP VPN server and that I could surf the internet, check email, etc...etc.

    This screen, from the http://www.whatismyip.com site, verified to me that all traffic from my iPod Touch was being routed through the VPN tunnel to their server and back again. The public IP reported is different than what I see from my Win 7 laptop at the same time even though both the laptop and the iPod Touch are currrently on the same local LAN here.

    So getting back to your original problem I really don't know what is going on with Win 7, at least on my machine, and its built-in PPTP VPN server function. I'm not home now so I have no way of testing that functionality with a Windows VPN client.

    The bottom line though is that the PPTP VPN functionality in my iPod Touch works as I expect it to on your iPhone. It comes down to a server issue.

    I suggest you test your iPhone against this free VPN server to verify in your own mind that its working then figure out what you want to do next. What exactly do you want to do with the VPN if you can get it working on the Win 7 server PC, ie. file access, remote and secure web surfing, etc?

    Please NOTE: The free VPN service changes their access PASSWORD every 12-24 hours and idle sessions more than 4 hours old are automatically disconnected. See the notes at the bottom of their main page.

    I am getting the same error, everything OK with VPN, but cannot login to work computer.  I have just bought new laptop that is using Windows 7 Home. 

    1. Remote access to server not enabled (it is)
    2. The remote computer is turned off (it isn't)
    3. The remote computer is not available on the network.  (it is)

    Does someone have any other ideas I could try.  Have tried the different solutions below and no luck

    Thnx in advance

    THanks for the fast reply...

    I have used the first link to create my VPN on windows 7 which is set up. I am using wippies home so I will have to contact them to learn how to open the port for VPN but meanwhile I am trying to use my 3G connection to use VPN which doesn't work. My main goal is to get it to work with 3G. At the moment it does not work with 3G or wifi (need to open that port though first which i have contacted administration for). 

    This is the settings I am using on my iphone:

    If I turn RSA SecurID off and write the password and click on save. it seems to crash and return to main screen without any settings changed. I do not know why. The server ip is the same ip from the computer.

    The computer is connected to a switch so I am using the real IP unlike routers ip. 

    From the event viewer, I see this warning msg (EVENT ID 20171):

    "Failed to apply IP Security on port VPN2-0 because of error: A certificate could not be found.  Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate..  No calls will be accepted to this port."

    "Failed to apply IP Security on port VPN2-1 because of error: A certificate could not be found.  Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate..  No calls will be accepted to this port."

    "A certificate could not be found. Connections that use the L2TP protocol over IPsec  require the installation of a machine certificate, also known as a computer  certificate. No L2TP calls will be accepted."

    I am assuming the problem is from the computer side rather than 3G network or iphone. Is that true?

    FWIW I just setup an Incoming VPN connection on my Win 7 Home Premium laptop following the instructions in the first link I posted. Next I setup a VPN connection on my iPod Touch (4th gen device) and successfully connected over my home wireless LAN.

    More help from Apple...

    So now the question is what will I do with the connection...:-)

    I think the VPN is not set up right on my win7. Any guide or help will be appreciated. 

    See this from MSFT for help setting up a PPTP VPN server on your Win 7 computer...

    http://windows.microsoft.com/en-US/windows7/Set-up-an-incoming-VPN-or-dial-up-connection

    ...or this page written for Vista. Its essentially the same...

    http://theillustratednetwork.mvps.org/Vista/PPTP/PPTPVPN.html

    Rember that if the Win 7 PPTP VPN server PC is behind a router or standalone firewall you need to forward/open TCP Port 1723 to the static (preferred) LAN IP of that PC. Also the router or firewall needs to be able to pass GRE Protocol 47 traffic. That is sometimes called PPTP Pass Through or VPN Pass Through depending on the manufacturer. Some firewalls and routers, including the built-in Windows Firewall, pass GRE Protocol 47 traffic automatically when TCP Port 1723 is opened.

    You can test the link by running the test detailed in the PPTP Ping and VPN Traffic sections on this page.

    http://technet.microsoft.com/en-us/library/bb877965.aspx

    To test over you home LAN don't use the public IP of the router or the PPTP server PC. Many consumer grade routers don't handle the loopback properly. Use the LAN IP of the server.
