[Samba] samba - wins? dns ? ldap?

[infolistas listas]

Hello users,
I'm having the floowing problem, I just configured a new machine with
ubuntu+ ldap + samba, all conections are OK!, I've set up the users and
machines for the domain , testparm says everything is ok, but when trying to
add a windows 2000 machine on the domain I get a message that alerts a
possible problem with the dns.
I thought I forgot to configure the wins but it was there.
ANy Ideias? the message is in Portugues and I'm not sure my translation will
follow the english standards

thanks.
