VPN Connection - ConnMgrEstablishConnection - Error 80070057

Hi,
I have developed an application to establish VPN Connection
programmatically.
I have followed these steps and I getting Error: 80070057

A/c to MSDN, the error implies one or more invalide arguments. Can
anyone plz let me know what's the error in the code:



GUID destNet = { 0x1CA3AF08, 0xEDE3, 0xF66C, { 0xB1, 0xA7, 0x64, 0x3C,

0x64, 0xDE, 0x35, 0x74 } };


The above destNet GUID is taken from the Registry value for the VPN
Entry created manually.

We can also create the VPN Entry programmatically.



CONNMGR_CONNECTIONINFO ConnInfo={0};
ConnInfo.cbSize=sizeof(ConnInfo);
ConnInfo.dwParams=CONNMGR_PARAM_GUIDDESTNET;
ConnInfo.dwFlags=0;
ConnInfo.dwPriority=CONNMGR_PRIORITY_USERINTERACTIVE;
ConnInfo.bDisabled = false;
ConnInfo.bExclusive = false;
ConnInfo.guidDestNet = destNet;


if ((hr = ConnMgrEstablishConnectionSync(&ConnInfo, phConnection,
60000, pdwStatus)) != S_OK &&
(int)pdwStatus != CONNMGR_STATUS_CONNECTED)
{
printf(("Function Establish failed (0x%08x). %02X, %02X\n",
GetLastError(),hr,(int)pdwStatus));
}
else if((int)pdwStatus == CONNMGR_STATUS_CONNECTED)
{
printf(" VPN Connection Successful"));
return SUCCESS;
}




thanks
Phani

Is this a GUID of your VPN connection? In this function you should use a
GUID of the destination network, not a GUID of the connection. If your VPN
connection connects you to "My Work Network" (default case) , use
IID_DestNetCorp as ConnInfo.guidDestNet.

I am unable to establish the VPN Connection.

The device is trying to connect to VPN server in US, which is in India.


Please let me know if u have any solution.

Could you post your code snippet?
