samba - Feb 2004 - Help with making samba-3.0.0 PDC and adding a XP/Pro client (and domain user accounts)

I would like to understand how to make my samba-3.0.0 (-15, from Fedora Core 
1) a PDC and how to make a XP/Pro box member of that domain and to add a 
domain user account, and eventually to ad a few more linux boxen as domain 
members into that domain.

This is the output of the PDC box testparm (the PDC box has two eth 
interfaces, only eth1 (192.168.1.* and 127.0.0.1 should access the PDC):

[root@fw samba]# testparm

and domadm contains only one member, chj (that's me), and domusers a few 
users, machines contains two machines, luddes$ (the XP box) and calles$, a 
Fedora Core 1 linux box, supposed to become a domain member.

/etc/samba/smbpasswd contains among others the ones in domadm and domusers as 
well as calles$ and luddes$, the two machines.

I managed to add the XP box to the domain, but I can't add a domain user 
account, J-SON/chj. I get a trust problem, something like "couldn?t
establish
a trust relation between this workstation and the primary domain". (Windows
XP
Swedish).
>From the log files, I can see these few "interesting" things:
[2004/02/08 19:39:16, 1] 
nmbd/nmbd_incomingrequests.c:process_node_status_request(324)
  process_node_status_request: status request for name J-SON<1c> from IP 
192.168.1.1 on subnet UNICAST_SUBNET - name not found.

[2004/02/09 09:40:57, 0] smbd/service.c:make_connection_snum(620)
  Can't become connected user!




Any help is appreciated.
