[cifs-protocol] Servers Hangs with Microsoft Office

I have an ubuntu box (10.04 LTS) with samba 3.4.7 and a particular configuration :
I have a filer A witch export a share in CIFS, this share is also export on another filer B (it is a proprietary replication, I can't modify any options) and this B filer can't export this "replication" of the A Volume in CIFS, only in NFS (The volume on the filer B was a kind of cache of the volume on the filer A) , so I mount this cache volume on my Samba (I lose the acl on the files but it's ok because the A volume is read only on the filer B).
When a user open an office file (With Read/Write) on the filer A, if another user try to open it on the Samba, the office (2003/2007/2010 on windows XP SP2/SP3 Vista and Seven) hangs and the samba hang too on this share so nobody can access to it until the file on the filer was closed.
I suspect the oplock option but I can't find the good option with the good argument.
Here my smb.conf
unix charset = ISO8859-15
workgroup = MYDOMAIN
realm = MYDOMAIN.FR
server string = SAMBA
security = ADS
password server = MyActiveDirectoryServer.mydomain.fr
log level = 3
log file = /var/log/samba/log.%m
max log size = 50
min protocol = NT1
getwd cache = No
paranoid server security = No
name cache timeout = 0
printcap name = cups
add machine script = /usr/sbin/useradd -d /var/lib/nobody -g 100 -s /bin/false -M %u
idmap uid = 20000-30000
idmap gid = 20000-30000
template homedir = /home/winnt/%D/%U
winbind separator = +
winbind enum users = Yes
winbind enum groups = Yes
winbind use default domain = Yes
block size = 4096
# oplocks = no
# level2 oplocks = no
path = /Data_Communes_Tls/Qualite
# fake oplocks = yes
locking = no
# veto oplock files = /*.doc/*.DOC/*.docx/*.DOCX/*.xls/*.XLS/*.xlsx/*.XLSX/
guest ok = Yes
The commented lines (#) are the try I made with no success.
This is only when I open the original file on Read/Write , the read only right on the file didn't cause any trouble...
Please Help, this problem make me crazy...
