[Samba] winbind problem with BUILTIN?

[Robert Fitzpatrick]

I shut my Samba PDC and all members down for some PC rearranging and now 
having an issue with one member server on Ubuntu 10.12 with Samba 3.5.4 
after restarting all. It would not connect, I tried to remove the 
computer name from LDAP and re-join the domain, that was successfully 
joined and the entry reappears in LDAP, but it times out when trying to 
connect to that host via the network or smbclient on the local box. All 
other workstations (Win2003, WinXP) and the PDC (FreeBSD Unix) are 
working perfectly. Since it is timing out, I tried the IP address with 
smbclient and browsing  and it works. For some reason, my 
/etc/resolv.conf was empty, so I fixed, but still timing out. So, I 
looked at Winbind and found a potential issue with BUILTIN?...

I tried emptying the contents of /var/cache/samba, still no help. Here 
is smb.conf on the problem PC, which noting has changed since it last 
worked...

[global]
         netbios name = MEDIA
         server string = Media Server %v - Music, Videos and Photos
         workgroup = WEBTENT
         realm = WEBTENT
         security = DOMAIN
         log level = 10
         syslog = 0
         log file = /var/log/samba/%m
         max log size = 50
         smb ports = 139
         name resolve order = wins bcast hosts
         printcap name = CUPS
         wins server = 192.168.1.21
         ldap suffix = dc=webtent,dc=org
         ldap machine suffix = ou=Computers
         ldap user suffix = ou=Users
         ldap group suffix = ou=Groups
         ldap idmap suffix = ou=Idmap
         ldap admin dn = cn=Manager,dc=webtent,dc=org
         idmap backend = ldap:ldap://mail.webtent.org
         idmap uid = 10000-20000
         idmap gid = 10000-20000
<snip shares>

Can someone help me determine the next step in tracking down this issue? 
Or, how I could start all over with this box (already tried re-join)?

Thanks, Robert
