problem to join PDC with 2 samba(PDC and member)

[Brunet Eric]

Actually, it runs a Samba PDC(2.2.0, called A) with MS 
client(W98,NT4,W2000), all works fine.
But i want to join another samba(2.2.2, called B) in order to share a 
printer for clients.

After read many many documents, i don't solve the problem:

This is kernel logs (debug flag to 1) when i try to access an resource 
of B with an account of PDC:

i follow docs:
- create machine account on PDC for B
# uadduser -n -d /dev/null -s /bin/false B$
# smbpassword -a -m B

- join B into PC
# smbpasswd -J OFFICE -m A
i had this message:
 >2001/11/15 15:42:09 : change_trust_account_password: Changed password 
for domain OFFICE.
 >Joined domain OFFICE.
The first message is normal?? if yes: which password i must change?? 
machine account don't have password!

last question:
is it possible: 2 samba: 1 PDC and 1 member ???
Because in docs, faqs archive list... i read NT for PDC and samba for 
member (vice versa) but never my situation.

PLEASE help :~(
