    Proxy Servers can demand authentication just like web servers do.
    When you are on an Intranet environment, IE takes care of sending
    your current credentials so you don;t see this in action unless you use a
    netmon.

    1) If you want to specify credentials to a proxy server, do the following
    If you want to use the same settings as IE does
    WebProxy wp = GlobalProxySelection.Select as WebProxy;
    wp.Credentials = CredentialCache.DefaultCredentials;

    or
    If you have your own custom proxy that is different from IE
    WebProxy wp = new WebProxy(....)
    wp.Credentials = CredentialCache.DefaultCredentials;

    2) If you want to set credentials to a server

    HttpWebRequest .hr = ...
    hr.Credentials = CredentialCache.DefaultCredentials;

    |Does the proxy you're using require authentication?
    |Remember that you deal with two possible sets of credentials here... those
    |attached directly to the webservice client are used to access the
    |webservice, while you can have a second set of credentials attached to the
    |HTTP Proxy object that are used for authentication against the actual proxy
    |server on your network...
