Cause: In my case, the cause was incorrect proxy server configuration due to which WinHTTP could not go onto the internet.
Solution: We would need the utility ProxyCfg to configure proxy configuration for WinHTTP services. This is an inbuilt tool on Windows 2003 server. Use this tool to configure proxy server setting:
ProxyCfg -p <ProxyServer:PORT>
This would configure WinHTTP server to go through my Web proxy ‘MyServer’ on port 80
If you already have IE configured with Proxy server configuraiton, you can copy those settings for WinHTTP by using the command:
The above command will simply download Internet Explorer’s Proxy configuration for WinHTTP.
For Windows 2008 and later, we do no have Proxycfg utility. We need to use Netsh WinHTTP command.
For displaying the current setting: Netsh WinHTTP Show Proxy
For configuring Proxy server: Netsh WinHTTP Set Proxy <Servername:80>
