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, 5] auth/auth.c:check_ntlm_password(271) check_ntlm_password: sam authentication for user [dario] FAILED with error NT_STATUS_WRONG_PASSWORD [2004/02/09 14:51:27, 3] auth/auth_winbind.c:check_winbind_security(80) check_winbind_security: Not using winbind, requested domain [MUNDY] was for this SAM.

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.
