[Samba] Help with NT domain

[Pérez Marfil Alberth David]

Hi listers,
i was using old samba 2.2.3 or similar 
this week upgrade the samba to 2.2.8a
to keep mi users list and conf backup the following files
smb.conf
smbpasswd

after the succefull install (FreeBSD Ports)
i restore the files to the apropiate directory

the clients are the same (win2k sp2) boxes,
i have to remove all machine account from smbpasswd
and recreate again with
smbpasswd -a -m machine$

from the clients i can't log to the domain and i got the message that the
workstation account
dos not exist into domain or bad password.
in the samba log i have something like
[2003/08/15 12:17:52, 0] rpc_server/srv_samr.c:api_samr_set_userinfo(670)
  api_samr_set_userinfo: Unable to unmarshall SAMR_Q_SET_USERINFO.
i try take off the client from the domain and move it to a workgroup and
back agian
windows say welcome to the domain but after restart a got the same message

any help are welcome....
