Hello to all, My samba servers are doing strange things . I?ve set up a smba-ldap as PDC and another as BDC. Everything was ok until last week. Suddenly all clients log on to my BDC not longer to the PDC. Testparm didn? t show any changes the PDC results Server role=ROLE_DOMAIN_PDC and the BDC Server role=ROLE_DOMAIN_BDC. I put the os level of the PDC to 240 and the BDC?s to 86 nothing changed. I also changed the Preferred master to no. How can I force the xp and vista clients only to log on to the PDC?
