Error

I got "Unable to connect to the remote server error" when I tried to call a webservice that is hosted on some remote machine outside my firewall. I am using a proxy server, and figured it that my application is not aware of the proxy server. So I did some googling and add the following defaultproxy settings under System.net tag in applications web.config file.

(provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified)”
