Hi, i'm having trouble since we migrated Nt4 to ADS, i've a samba (3.0.20b) box, acting as ADS Domain Member,net ads join, winbind and kerberos is fine, i'm able to work with domain members to the samba box, no problems so far. Problems are workstations and laptops from home users, they are not part of the domain, those people can not log in, the samba log says NT_STATUS_INVALID_COMPUTER_NAME, the account names selfs already exists from the older Samba 2.x configuration, the strange thing is that this bevavior is not permanent it appears and disappears from time to time. Anybody can point me into the right track ? Many thx. Matt.
