Upgrade Ubuntu 8.04 -> 10.04 : Samba PDC KO

Bonjour,



J'ai migrer mon serveur Ubuntu en 8.04 vers du 10.04...
Depuis mon Contrôleur de domaine ne fonctionne plus (qui fonctionnait très bien avant pendant 2 ans)...

A la connexion Windows j'ai le message suivant : Le contrôleur de domaine n'existe pas ou est indisponible ou votre compte d'ordinateur n'a pas été trouvé.

Sur un autre poste je me suis sorti du domaine, je reboot, je tente un jonction depuis le poste de travail : Erreur dans la tentative de jonction au domaine : Accès refusé

Help me ...


Ci-dessous un extrait de ma conf
