Samba domaine pb ouverture session xp

Salut !

J'ai un samba en controleur de domaine. J'arrive a faire la jonction mais lorsque je reboot, je ne peux pas me logguer. C'est urgent car tout l'ecole ne peux plus se logguer. J'ai du casser quelque chose dans le smb.conf que voici :

[global]
workgroup = EICAR
server string = File server
interfaces = eth0
update encrypted = Yes
guest account = invite
passwd program = /usr/bin/passwd %u
passwd chat = *New* %n\n *Re* %n\n *pa*
username map = /etc/samba/smbusers
log file = /var/log/samba/log.%m
logon script = logon.cmd
logon path = \\%N\profiles\%u
logon drive = H:
domain logons = Yes
os level = 65
domain master = Yes
dns proxy = No
panic action = /usr/share/samba/panic-action %d

[netlogon]
path = /home/%g/netlogon
write list = root
browseable = No

[homes]
comment = Repertoire personnel
read only = No
create mask = 0700
directory mask = 0700
browseable = No

[profiles]
path = /home/export/profile
read only = No
create mask = 0700
directory mask = 0700
browseable = No

[Public]

path = /partage/Public
read only = No
create mask = 0777
directory mask = 0777
guest ok = Yes
wide links = No

[Animation]
comment = Repertoire section Animation
path = /home/Animation
valid users = root, @Animation
read only = No

[Personnel]
comment = Repertoire du personnel formateur et administratif
path = /home/Personnel
valid users = root, @Personnel
read only = No
directory mask = 0770

[Realisation]
comment = Repertoire section Realisation
path = /home/Realisation
valid users = root, @Realisation
read only = No

[Image]
comment = Repertoire section Image
path = /home/Image
valid users = root, @Image
read only = No

[Logiciels]
comment = Repertoire de logiciels
path = /partage/Logiciels
valid users = root, @Personnel
read only = No
create mask = 0770
directory mask = 0770

[Montage]
comment = Repertoire section Montage
path = /home/Montage
valid users = root, @Montage
read only = No

[Son]
comment = Repertoire section Son
path = /home/Son
valid users = root, @Son
read only = No

[TSN]
comment = Repertoire section TSN
path = /home/TSN
valid users = root, @TSN
read only = No

[Cinergie]
comment = Repertoire Cinergie
path = /home/Cinergie
valid users = root, @Cinergie
read only = No

Si quelqu'un a une idée je suis preneur !

Merci!
