XP Pro, Samba 3 profile share authentication

I have really weird problem with XP Pro and Samba 3 (I tried 3.0.1 and
3.0.2). Samba 2.2.8a works with no problem.

I can login with no problems. But when I login and logout few times
(sometimes one, sometimes five times) then XP can not load roaming profile
from the server (login still works). I can access to all shares with no
problems. The only way to fix that is to restart XP machine. And then again
same thing happens.
I checked log (level 10) and found this:

[2004/02/09 14:51:27, 3] libsmb/ntlm_check.c:ntlm_password_check(282)
  ntlm_password_check: NT MD4 password check failed for user dario

[2004/02/09 14:51:27, 10] auth/auth_util.c:free_user_info(1281)
  structure was created for dario

It looks to me that authentication has failed, but previous authentication
passed (first one, login). This one is to access to profile share. After
that all authentications are ok, even profile during logout.

Let me say once more, this starts to happen after few logins and logouts and
restarting computer clears this problem, at least for some time. Everything
else work fine all the time.

I tried everything I know (different smb.conf and XP security and registry
settings), but it did not help.
