Hello, I am trying to build a test network that uses Samba running on Linux for domain control. The Samba version is 3.0.25a. The linux versions are Fedora Core 6 and Fedora Core 3, both with all patches applied. Authentication is by tdbsam. I have succeeded in setting up the Fedora Core 6 machine as a Primary Domain Controller. I can add WinXp and Win2K machines to the domain on the fly. Domain logons work. Roaming profiles work. Unix password synchronization works. Now I want to set up the Fedora Core 3 machine (named lsr-oh5) as a Domain Member Server with winbind authentication, but I am having some problems. This is the smb.conf file for lsr-oh5, the DMS machine: [global] netbios name = LSR-OH5 workgroup = LSR-DOMAIN encrypt passwords = yes server string = Samba Member Server security = domain password server = LSR-JWMTST encrypt passwords = yes idmap uid = 200000 - 300000 idmap gid = 200000 - 300000 winbind enum users = yes winbind enum groups = yes wins server = 10.1.0.209 log file = /usr/local/samba/var/log.%m max log size = 50 passdb backend = tdbsam [tmp] comment = Temporary file space path = /tmp read only = No guest ok = Yes browseable = yes [public] comment = Public Stuff path = /home/samba read only = No guest ok = Yes browseable = yes The nscd deamon is not running on either the PDC or the DMS. I can join the DMS to the domain with or without the -S argument; running "net rpc join -S LSR-JWMTST -Ujwm%password" or "net rpc join -Ujwm%password" gives Joined domain LSR-DOMAIN I copied libnss_winbind.os and libnss_wins.so to /lib and created symlinks from the libraries to .so.2. I edited /etc/nsswitch.conf and added winbind to the passwd and group serverices. After starting winbindd running "wbinfo -u" gave LSR-DOMAIN\kaf LSR-DOMAIN\jwm "wbinfo -g" gave BUILTIN\administrators BUILTIN\users LSR-DOMAIN\server admins LSR-DOMAIN\domain admins "getent passwd" gave snip rivoxy:x:73:73::/etc/privoxy:/sbin/nologin jwm:x:325:214:John W.

LSR-OH5 is displayed in Network Neighborhood under domain LSR-DOMAIN and running "net view" in a command window gave Server Name Remark -------------------------------------------------- \\LSR-JWMTST Samba Primary Domain Controller \\LSR-JWMVEX Vex \\LSR-OH5 Samba Member Server So far, so good. However running "net view \\LSR-OH5" gave System error 53 has occurred. The network path was not found. Further, LSR-OH5 disappears from Network Neighborhood and the output of the "net view" command after a short interval. I would appreciate it if any one can give me an idea as to how to solve this problem. Thanks
