Debian 2.6.18

smb.conf:

[global]
        workgroup = DOMAIN
        server string = %h server
        interfaces = eth0
        passdb backend = tdbsam
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
*Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
        syslog = 0
        log file = /var/log/samba/log.%m
        max log size = 1000
        name resolve order = lmhosts host wins bcast
        add user script = /usr/sbin/adduser --quiet --disabled-password
--gecos "" %u
        domain logons = Yes
        domain master = Yes
        dns proxy = No
        wins support = Yes
        panic action = /usr/share/samba/panic-action %d

After following the instruction here:

http://archives.free.net.ph/message/20060316.164348.49db1fcd.en.html

I now get an additional error appearing before other net rpc response:

[2008/01/18 10:07:43, 0] param/loadparm.c:handle_copy(3147)
  Unable to copy service - source not found:

//

I want to run the linux samba server as PDC. After some reading I am not
completely clear if the correct approach is: join PDC machine to domain
always; optionally use winbind. I take it also at this point there is no
requirement to set up default windows domain groups.

However, doing so, log.nmbd shows:

[2008/01/18 11:01:15, 0] param/loadparm.c:handle_copy(3147)
  Unable to copy service - source not found:
[2008/01/18 11:01:15, 0] auth/auth_util.c:create_builtin_administrators(785)

  create_builtin_administrators: Failed to create Administrators

Thanks for any advice.
