When I want to load an RSS file using its URL, below error will be appeared: A socket operation encountered a dead network _[IP Number]_ Maybe the problem is because of using a proxy server for internet connection. I've used Isa-Server to connect to internet. So I tried to use NetworkCredential but it can't solve the problem:

 System.Net.NetworkCredential networkCredential = new System.Net.NetworkCredential(myUserName, myPassword, myDomain);

 XmlUrlResolver xmlUrlResolver = new XmlUrlResolver();
 xmlUrlResolver.Credentials = networkCredential;

 XmlReaderSettings xmlReaderSettings = new XmlReaderSettings();
 xmlReaderSettings.XmlResolver = xmlUrlResolver;

 XmlReader xmlReader = XmlReader.Create(txtRssUrl.Text.Trim(), xmlReaderSettings);

How can I load an RSS file using its URL?
