I'm so lost.... I've configured samba/ldap to act as PDC and everithing seems to work fine, i can join easily a domain with my w2k SP4 client but after reboot when i try to connect to samba PDC i obtain a message that say something like "the domain is not avaiable at the moment, try again later". what can i do... i'm seriously tired and angry... =) thanks everybody.
