samba - Feb 2003 - Duplicate name error when joining XP to Samba domain

Hi,

I'm having problems trying to join my XPpro boxes to a Samba (2.2.7a)
domain. I was able to get 1 XP box to join (the very first one) but the
rest complain about a duplicate name on the network just after I
enter the root/pw when joining the domain. None of the smb user names are
in common with the machine names.

The NT4 workstations have no problem joining the samba domain. All
workstations were previously on another PDC (an NT4 server on the same
network). DHCP server is on a Linux firewall and all machines get the
same IP lease based on MAC address. 

Here's what I've tried:

- Checked /etc/passwd and /etc/samba/smb.conf to ensure machine name entry
correct. 
- Ran "net use * /delete" to make sure no connections present.
- Moved from Domain1 to Workgroup and tried to move to Domain2. 
- Changed the SID on the second XP box (just in case workstations were built
with Ghost)
- SignorSeal registry hack applied (forgot actual name).
- Disabled Domain member: Digitally encrypt or sign secure channel data
and Domain member: Digitally sign secure channel data (when possible)
- Turned off NT4 PDC (workgroup = GLASS)
- Tried workgroup = GW (just in case GLASS and GLASSWORLD perceived to be the
same domain)

Portion of my smb.conf:

[global]

   workgroup = GLASSWORLD
   netbios name = TS1
   server string = Samba Server
   printcap name = /etc/printcap
   load printers = yes
   printing = cups
   log file = /var/log/samba/%m.log
   max log size = 5000
   security = user
   encrypt passwords = yes
   smb passwd file = /etc/samba/smbpasswd
   unix password sync = Yes
   passwd program = /usr/bin/passwd %u
   passwd chat = *New*password* %n\n *Retype*new*password* %n\n \
*passwd:*all*authentication*tokens*updated*successfully*
   pam password change = yes
  obey pam restrictions = yes
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   dns proxy = no
   username map = /etc/samba/smbusers
   admin users = root, administrator
   domain logons = yes
   domain master = no
   logon drive = X:
   logon home = \\ts1\%U
   logon script = logon.bat
   logon path = \\ts1\profile\%U
   os level = 99
   preferred master = yes
   wins support = yes
   log level = 3
   time server = yes


Any suggestions appreciated. Just shout if you need some diagnostics.

Thanks,
Stephen

FYI, it turns out that it was a DNS problem. Once I added the workstation
names and corresponding IPs to the Samba PDC /etc/hosts file, the XP boxes
happily joined the new domain.

BTW, contrary to above, you do need "domain master = yes" and the bit
about only the first XP box being able to join the domain was probably a
red herring. I don't know why though.
