Hello Due to the migration from my old server Linux Debian Woody / Samba 3.4 (PDC, wins server, without windbind without ldap, with smbpasswd passwd backend) (hardware obsolete) to a new server with Debian Lenny Linux / Samba 3.4.8 (backport) and the same configuration (PDC WINS server without windbind without ldap, with smbpasswd passwd backend) I am unable to join new windows computer to domain and if I disconnect a computer already connected, I am unable to reconnect. I have the following error message in log.nmbd: wins_registration_timeout: WINS server 127.0.0.1 timed out registering IP 192.168.9.104 (ip PDC) message on the computer Win XP at the junction to the domain: "A domain controller for domain XXXX could not be contacted" the computer account has been created on the samba PDC. the WINS is configured on the new and old computer. no firewall enabled on the server or on computers. ping to the server is OK If I connect locally on the computer as an administrator, I can access the samba server and its shares through Network Neighborhood. (User administrator exist in the samba server and is the domain administrator). no error in the samba log for that computer except a trace of access made from the Network Neighborhood computers that were already connected to domain before migration have no problem. smb.conf : # Global parameters [global] unix charset = ISO8859-1 display charset = ISO8859-1 workgroup = MAIRIE server string = Serveur %h (Samba %v) security = user log level = 4 log file = /var/log/samba/log.%m time server = Yes printing = cups printcap name = cups show add printer wizard = No logon script = %U.bat logon path logon home logon drive domain logons = Yes os level = 255 preferred master = Yes domain master = Yes wins support = Yes dns proxy = No name resolve order = wins host bcast lmhosts passdb backend = smbpasswd ldap ssl = no admin users = xxxxx,yyyy,administrateur nt acl support = No hide special files = Yes guest account = nobody [homes] comment = Repertoires personnels des utilisateurs path = /home/samba/utilisateurs/%U username = %S valid users = %S read only = No browseable = No [netlogon] comment = Chemin de demarrage des scripts de connexion path = /home/scripts browseable = No guest ok = Yes read only = Yes Have you any ideas to solve this problem?
