Answer 1

Possible solutions can be:

1) add <identity impersonate="true"></identity> in web.config

2) If you have credentials

using (client = new MyWebService())
{
    var username = ConfigurationManager.AppSettings["WSUserName"]
    var password = ConfigurationManager.AppSettings["WSPassword"]
    client.Credentials = new NetworkCredential(username, password);
    // .. and the call here ..
}

Let me know if it doesn't fix your problem.
