Prob smbpasswd (urgent)

quand je me connecte sur un de mes postes client win98 il me met "le portage est introuvable assurez-vous que le type a été entré correctement"
voila mon smb.conf :
[global]
workgroup = ***
netbios name = serveur
server string = Server du lycee
log file = /var/log/samba/log.%m
max log size = 50
log level = 3
guest account = pcguest
security = user
password level = 4
username level = 4
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
username map = /etc/samba/smbusers
os level = 33
domain master = yes
preferred master = yes
domain logons = yes
logon script = script.bat
logon home = \\serveur\%u
wins support = yes
dns proxy = no

[homes]
comment = repertoire de %u
browseable = no
writable = yes

[netlogon]
comment = service de connexion reseau
path = /home/netlogon/%g
browseable=yes

[classes]
path = /home/classes
browseable=no
write list=@profs

[partage]
comment = répertoire de partage
path= /home/partage
browseable=yes
write list=profs

merci de votre réponse
