System.Runtime.InteropServices.COMException (0x80072EE2): The operation timed out HResult=-2147012889

I have a weird one over here;

I have built a small vb.net app using classic vbscript to send Soap Strings across Oracle CRM On Demand.

Everything works perfectly fine on my machine or on any other machine which is not connected to a VPN or within a company network.

So when I try to run the app on another machine which is on a company network i get the following error;

So according to the above error desc., it failed on the LINE 150 which is;

objXMLDOC.send(SoapStr.ToString) - LINE 150 Also line 2061 is just calling the Private Sub which has the code for sending the SOAP request.

Now with that machine being connected to a restrictive VPN or connected to a restrictive company network, I understand that there could be one of the Proxies is not letting the Soap URLs pass through for some reason. 'BUT' I have tried to access every single URL (that i am using in my code) via IE and other browsers and I access them without any problems. And (if I am not wrong) VB.NET Apps is based on same/ default user settings as IE. With that said, i have also got the following in my "app.config" file which should hopefully consider to take same internet/proxy settings as set in IE;

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.net>
      <defaultProxy useDefaultCredentials="true">
        <proxy usesystemdefault="True" />
      </defaultProxy>
    </system.net>

Also, after searching for hours on web, it seems like there "MIGHT" be an issue with registry. But i am really not sure what exactly to go and deal with this further.
