Hi, I have a small network with several Windows XP clients and an Ubuntu server (7.10) running Samba (3.0.26) as a Domain Controller but can't get the clients to login to the domain. Here's my smb.conf: [global] name resolve order = wins lmhosts host bcast idmap gid = 10000-20000 passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* . obey pam restrictions = yes admin users = test frc @Admin passwd program = /usr/bin/passwd %u dns proxy = no netbios name = SRV-01 writeable = yes printing = cups idmap uid = 10000-20000 local master = yes workgroup = CYSOL os level = 65 printcap name = cups security = user max log size = 1000 delete user script = /user/sbin/userdel -r %u log level = 3 log file = /var/log/samba/log.%m load printers = yes add group script = /usr/sbin/groupadd %g socket options = TCP_NODELAY delete group script = /usr/sbin/groupdel %g add user to group script = /usr/sbin/usermod -G %g %u logon drive = L: domain master = yes interfaces = 127.0.0.0/8 eth0 encrypt passwords = yes logon home = \\%N\%U printer admin = test frc @Admin passdb backend = tdbsam template shell = /bin/bash wins support = true server string = %h server (Samba %v, Ubuntu) path = /usr/network/ unix password sync = no logon path = \\%N\%U\profile add user script = /usr/sbin/useradd -m %u valid users = test frc @Admin syslog = 0 panic action = /usr/share/samba/panic-action %d domain logons = yes #winbind enable local accounts = no #winbind trusted domains only = yes #winbind enable local accounts = no All the client machines have been added to samba as machine trust accounts and users have been added too. In Windows, I can join the domain with the user 'frc' which succeeds and brings up the message 'Welcome to the domain CYSOL'. Its only after restarting and trying to login at startup that it brings up the standard message saying the domain controller is unavailable or machine account not found. testparm shows the server as a PDC with no errors. Here's some lines I've picked out from a few of the logfiles: smbd.log [2008/02/21 15:55:37, 3] smbd/connection.c:yield_connection(76) yield_connection: tdb_delete for name failed with error Record does not exist.

I'm considering uninstalling samba and reinstalling because i'm running out of ideas on this so any suggestions are appreciated. Please ask if you need any more info or logfile stuff. -- View this message in context: http://www.nabble.com/XP-clients-won%27t-login-to-samba-domain-tp15622813p15622813.html Sent from the Samba - General mailing list archive at Nabble.com.
