    Thanks for the reply, Michael. The problem is not definitely related to the
    webserver name since the problem happens when the authentication type is
    changed (everything else being the same).

    My internet search today has given me some clue. It looks like I need to set
    the "Credentials" for the service programmatically to "DefaultCredentials" in
    the client code.

    I donot know much about that topic and I am not sure why this is not done
    automatically. I am also surprised to learn that it needs to be done in the
    client programmatically. I have tried it and it seems to solve the problem I
    had. However, I need to find out and learn more about the topic.

    Regards,

    DownUnder.
