samba - Oct 2003 - Samba 3.0.1Pre1 and windows 2000, domain problem

Hi,
 
    I'm using samba-3.0.1pre1-1 (rpm)  and I'm trying to make it as a
PDC. 
 
    Using WindowsXP Pro I'm able to join the domain I've made in samba. 
 
    The problem is that when I try to join the domain using a Win2000
I'm able to join the domain using 'Network
Identification->Properties' ,
but when I try to add a user in control-panel from the domain I got the
following error : 
 
    "The Trust relationship between this workstation and the primary
domain failed"
 
    I'm using samba with smbpasswd (this is a test machine)  and I've
added the machine and user account.
 
    I tried to enable netbios over TCP in w2000 to see it it changed
anything, but it made no difference.
 
 
    Any tips?
 
 
commands and configuration
 
 /usr/sbin/useradd  -g machines -d /dev/null -c 'test'  jungletres$  -s
/sbin/nologin
 smbpasswd  -a -m jungletres
