2003 server in a 2000 AD environment

Hi all,

We have the following setup.

1 pdc 2000 server
2 member servers 2003

1 of the members servers is a dedicated appliaction server, the other
one the mailserver.

On the application server I can browse the AD for users/objects
without problems, on the mailserver however, I can only browse the
local userlist, so I can't add any users from the global AD to any
local groups.

Both servers are installed identically and no additional AD config was
done on the appl. server.

Has anyone else had similar probs and what can we do to make the
mailserver able to browse the glbal AD too ??
Met vriendelijke groet/Kind Regards,
