I have Samba 3.0.4 running on Slack 9.1. I set PDC. Clients are win98, winnt4, w2k and winxp. All of them can connect to Samba shares, but they cannot access each other. I got an error message indicating that there is something wrong with trust relationships. I created machine and user accounts correctly. My smb.conf: [global] workgroup = firma netbios name = serwerek server string = Serwer firmowy encrypt passwords = Yes hosts allow = localhost, 10.0.0.0/255.255.255.0 log file = /var/log/samba/log.%m max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 logon path = \\%L\Profiles\%U logon home = \\%L\%U\.profiles wins support = yes domain logons = yes os level = 65 domain master = yes local master = yes preferred master = yes name resolve order = wins hosts lmhosts bcast time server = true Best Regards Cooba
