samba - Jun 2003 - samba + winbindd + w2k

Hi,
I have configure my samba to take the authentication in the w2k pdc ....
To authenticate in my w2k I?m using the winbind ..
When i try to view my shares (samba) into the my windows workstation always
ask me for a user and password,
 and when i put my user and password , ask for them again...
My config files :
####smb.conf#######
[global]
workgroup = MP
template homedir = /home/%U
template shell = /bin/null
server string = Samba Server
log file = /var/log/samba/samba.log
log level = 1
security = domain
password server = dc01.intranet.mp.ba.gov.br
encrypt passwords = yes
writable = yes
smb passwd file = /usr/bin/smbpasswd
wins server = 10.43.4.1

preferred master = False
local master = No
domain master = False


winbind use default domain = yes
winbind separator = "\"
winbind uid = 10000-20000
winbind gid = 10000-20000
winbind enum users = yes
winbind enum groups = yes

[homes]
   comment = Home Directories
   browseable = yes
   writable = yes
   valid users = gustavo_b

 You are not being authenticated:
 Did you successfully join the domain with the smbpasswd -j DOMAIN -r
SERVER command before starting winbind?
 Did you modify /etc/nsswitch to use winbind?
 Did you then start winbind?
 What do the logs say?
