hi, i have a working PDC / BDC setup with both samba v3. my question is related to failover: is the following config right for a correctly configured network browsing and name resolution (especially for clients)? PDC Config: local master = yes preferred master = yes domain master = yes os level = 120 domain logons = yes wins support = yes BDC Config: domain master = auto os level = 65 domain logons = yes if PDC fails, normally BDC should recognize that and become a domain master with this config, right? is there any error in reasoning with "wins support = yes" and a failing PDC? may be you have some more experience and a 100% working smb.conf regarding browsing (PDC/BDC). thx in advance, greez -- Michael Gasch Max Planck Institute for Evolutionary Anthropology Department of Human Evolution (IT) Deutscher Platz 6 D-04103 Leipzig Germany Phone: 49 (0)341 - 3550 137
