the said website can be connected through windows forms application. i am able to open through browser.
when i connect to internet through dongle, i can connect to the said sms gatewary (smscountry.com) and send sms from windows service application.
but when the same service is connected through office lan ( internet through proxy server) , i am getting the above error message.
however i am able to open Smscountry.com through webbrowser and windows forms application
I feel it is definitely has to to do with proxy settings. how can i resolve this.
