to connect from my Friend's system which is behind a firewall, I was annoyed
by seeing the following error message : "the underlying connection was
closed: Unable to connect to the remote server."

at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult)
at System.Net.HttpWebRequest.GetRequestStream()
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String
methodName, Object[] parameters)
