I wasn't aware that this was a change in SP1, but it sounds as if StrictNameChecking is enabled on your server after you've added SP1
(http://support.microsoft.com/default.aspx?scid=kb;en-us;281308)
 
You ca disable it in general by configuring the DisableStrictNameChecking reg-key as the KB above explains.  However, this would allow to access the server via _any_ name.   I typically suggest to use the reg-keys to limit additional names to those you really want:
 
DNS:
HKLM\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters\AlternateComputerNames (Multi-SZ)
NetBios:
HKLM\SYSTEM\CurrentControlSet\Services\lanmanserver\Parameters\OptionalNames (Multi-SZ)
 
This can also be done via the Win2003 version of NETDOM:
NETDOM COMPUTERNAME <current NetBIOS or DNS name> /add:<additional FQDN name>

Subject: [ActiveDir] Windows 2003 sp1 DNS problem


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?

Adrião
