samba - Feb 2003 - windows 2000 pro "successfully" joins samba domain, but domain user login fails after reboot.

hi,

i am having trouble with samba-3.0 acting as a domain controller. i
have been using samba-3.0-alpha17-19 acting as a pdc for windows
2000 workstations for a couple of months.

but now i have a problem joining windows 2000 pro.

i am manually creating a unix account for a new machine. and then i can
join this machine "successfully" to the samba domain. at least windows
2000 pro says, that it has successfully joined the domain.

but thats not true. if i am looking at the newly created samba account
for that machine, then i can see that the two password hashes for the
machine account are different!

and so, the windows 2000 pro machine cant authenticate itself to the
samba server when it is booting.



info:
i have tried both the ldapsam backend and the standard smbpasswd backend.
same results with both backends.
i have also tried using different versions of windows 2000 pro
including: no sp, sp2, sp3


hope that someone could clarify whats going wrong

tia
