Connecting to Web Services via Proxy

I have an Access application (don't ask) which uses a .Net component to connect to our web service. Some of the people trying to use the program are on corporate networks and have proxies that require authroisation. I have modified the component to specify the address and port number of the proxy and have tried to get it to pass through the Windows credentials, see code:

WebProxy prox = new System.Net.WebProxy(_proxy);
prox.Credentials = CredentialCache.DefaultCredentials;
service.Proxy = proxy;

It connects to the proxy ok but is still showing as an annonymous connection. Any idea how I get it to pass through the credentials of the current logged on user?

Many thanks

I encountred your problem and I used to use this as a solution and it works for me as well.
Then you have to implement the IWebProxy

public class MyProxy : System.Net.IWebProxy
        {
            public string User { get; set; }
            public string Password { get; set; }
            private System.Net.ICredentials _NetWorkCredential;
            public MyProxy(string User, string Password)
            {
                this.User = User;
                this.Password = Password;
                _NetWorkCredential = new System.Net.NetworkCredential(User, Password);
            }
            public System.Net.ICredentials Credentials
            {
                get { return _NetWorkCredential; }
                set { _NetWorkCredential = value; }
            }

            public Uri GetProxy(Uri oUri)
            {
                return new Uri(oUri.ToString());
            }

            public bool IsBypassed(Uri oUri)
            {
                return false;
            }
        }
And then move to the config file and parameter it

<defaultProxy enabled="true" useDefaultCredentials="false">
  <module type = "mynamespace.MyProxy, myAssemblyname" />
defaultProxy>

but your assembly should be place in the bin directory 
of the CMS application
