[ActiveDir] Windows 2003 sp1 DNS problem

[adriaoramos]

Hallow all.

        I need help in a problem I have after installing Service Pack 1

        This is the case:

        I have a windows 2003 Server (I Will call it SERVER01), without service pack 1
        I created a dns name like this

        aplicacao.mycompany.com

        Before installing SP1, when I called locally

        \\aplicacao.mycompany.com


        It opened shared folders perfectly

        Now , after SP1, if I call \\aplicacao.mycompany.com   It asks for a user and password. I don´t know witch password or user is that...

        If I call   \\SERVER01.mycompany.com, it works.....

        What was changed after installing SP1?

        how can I correct that?
