  • In most cases, VPN error 807 is firewall or security software settings issue. I would double check the firewall settings.

  • Hi,

     

    Which is the type of your VPN?

     

    Please let us know if all computers in same network environment. If it is possible, please use windows 7 to test this issue in windows XP network environment which VPN worked fine.

     

    If this issue persists, please try the following steps in Windows XP VPN server to check what the result is:

     

    1.    Click Start, click Run, type regedit, and then click OK.

     

    2.    Locate and then click the following registry subkey:

     

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

     

    3.    In the right pane, make sure that the DisableTaskOffload registry entry exists. If this entry does not exist, follow these steps to add the entry:

     

    a)   On the Edit menu, point to New, and then click DWORD Value.

    b)   Type DisableTaskOffload, and then press ENTER.

     

    4.    Click DisableTaskOffload.

     

    5.    On the Edit menu, click Modify.

     

    6.    Type 1 in the Value data box, and then press ENTER.

     

    7.    Exit Registry Editor.

     

    Hope it helps.

  • Hi,

    I am using a built in Microsoft VPN. All computers are not in same network environment.I tried to test VPN to another VPN server(this server not using XP, not sure using what OS)  at another place  with my windows 7 laptop and it's work fine. I already add the registry entry as you instructed and still get same error 807. And now i have another problem, my PC using windows xp that before this can VPN also now suddently can't VPN anymore to that XP VPN server. i can only use remote desktop connection to remote to the VPN server. Anything else should i check? Thanks.

  • Hi,

     

    ERROR_VPN_DISCONNECT 807

     

    The network connection between your computer and the VPN server was interrupted. This can be caused by a problem in the VPN transmission and is commonly the result of internet latency or simply that your VPN server has reached capacity.

     

    You could try system restore in your Windows XP VPN server to get back to a previous good time point to check this issue.

     

    Meanwhile, if you connect your Windows 7 via router, I suggest that you temporarily bypass the router, and try to connect. If the issue does not occur, there are some settings on the router cause this issue.

  • Hi,

     

    According to your description, it should be a VPN server issue. Please kindly collect the following information:

     

    How did you built your VPN server in Windows XP?

     

    I would like to confirm if you are using third-party VPN server in Windows XP. If so, it is recommended to contact the software company for further help.

  • hi, sorry for late reply, i am using microsoft standard built in VPN, just follow standard wizard to create VPN server. No other 3rd party software. my windows xp running freeproxy so the whole network will go through that windows xp in order to connect to internet. if i disabled the freeproxy then the whole network can't access internet. i open port 1723 in router but i don't know how to open protocol 47 gre in router because i can't see any configuration about that. but i think that should be a problem because i can connect to the server when i disable local network adapter.only when i enable back the adapter then it will stuck when try to connect using pptp protocol..please what should i do next? thanks..

  • Hi,

     

    I am now have almost finally manage to solve this VPN issue, the problem i found is cause by network adapter binding order. when I  move external adapter to up of binding order then I can VPN, but there comes another problem, i can no longer access to local network, ping to local network server give request timeout. So, when i move internal adapter to top then i can access local network but again VPN fail to connect. I just want to know If there any setting that i can make to allow VPN connect without have to move the binding order, thanks for any help..
