Getting error "Unable to open VPN-Connection"
When opening a connection to our customer site using a Windows standard-PPTP it's sucessfully established.
But I'm receiving the error: "Unable to open the VPN-Connection, do you want to continue?"
The connection takes some more time for beeing established than usual. But when I have a PING -t command running in a command window, I notice that the ICMP-request starts coming back few seconds after I clicked "Connect" in RDP-Manager.
When I click on YES, the RDP-Connection is sucessfully established.
I there anything that can be configured to work around that issue?
All other PPTP-Windows-Connections work fine.

Could you try to increase the wait time delay?
David Hervieux
Hi,
thanks for your input.
If your're refering to the delay, which can be configured on the VPN Tab.
Yes - I've put 30 seconds in there. But the result is the same.
Yes I was referring to this delay. Could you enable the VPN debug with the "Show console error"

The Error message in German is translated as follows:
So there's no error.
As stated in my initial message I can even ICMP/PING the remote computer after few seconds.
Could it be possible that rasdial return a code different than 0? could you try to open the VPN in command line and check the return code?
David Hervieux
I created a small bat-file for validating this:
ErrorLevel is ZERO after connection is up.
I have to be honest, I won't be available for the next week and to help you I will need to create a special build some debug info. You will be my number one priority as soon as I get back to the office. In the meantime you could create a Generic VPN and use your batch file in it.

Could you try the new release. You should have an error code in the message.
David Hervieux
Here's a screen of the Message-Box from the new Release.
So it seems that we get an error code -1 from the executable. If you run the application in 64 bit, do you get the same error code?
David Hervieux
When I launch the 64-Bit Executable of RDP-Manager I get the following message.
The other PPTP-VPNs I'm using are still working, when I use x64 Mode.
What I could do is add a new setting called: "Ignore error code". This will allow you to continue and it will flag the VPN connection as failed.
David Hervieux
Hi David, that would be great!
Hi,
I was implementing the IgnoreErrorCode but I saw a wait for exit of 15 seconds. Could it be possible that it takes more than that to open the VPN?
David Hervieux
The VPN Connection comes up instantly and can be used for establising a RDP-Connection.
Maybe it takes some time for rasdial to return.
It would be best to have the setting you suggested for just executing the rasdial command and not taking care of any error code.
I could adjust the correct time it takes for the VPN to come up afterwards with the Wait Time Delay.
Hi,
This is already implemented internally. I will release the new minor version today with the setting.
David Hervieux
Hi David,
thank's for giving us the new setting.
The connection works without any errors now.
regards,
Tobias
With or without the setting? I've made a little tweak at the same time.
David Hervieux
The tweak did the trick.
I couldn't reproduce the error with the setting turned OFF and the VPN Connection could be established w/o any errors
