Error connecting to a web service

Hi,

I'm trying to connect to a SOAP Web Service from a page hosted on discountASP.net and I'm getting an exception "System.Net.WebException: Unable to connect to the remote server..."
The remote server is responding, and the application works from the in house test server. It only fails when executing from discountASP.net servers.

Are you guys behind a proxy? Why can't I connect to an external web service? Again this is happening on discountASP.net servers only, the service and the page work fine. The response I got from technical support was to post to the forum.

Any suggestions would be greatly appreciated.

Thanks,
Alex

They say they are not blocking access from any IP. And I can access their service from any other server I tested it from. The problemis only when connecting from discountASP.net site.

To debug I setup a page that does a HttpWebRequest to the IP like shown below:
