Strange behaviour with samba share

Hello.

One month ago i've mounted an omv nas, with the latest omv2 version.

After an aupdate and made the configuration for the connection to my AD, my nas seems to work well.

Most of my share was shared via "guest only" and "root" and "users" had all the rights on the share.

The problem was that if i use a "robocopy" script it create folder on the share, but nothing can be copied in (cannot acces).

If i use "xcopy" all works well

If i launch "robocopy" script it fail to put file, but not create directory. But if i stop, i open Windows explorer, just click "IN" the share and re-launch "robocopy" : it works ????

If someone can help me i thank it a lot.

No. The script was launch on a win server with admin account. But i've made test direct on the machine with the same account on a command prompt to view why there is a problem.

----------------------------edit----------------------------
Sorry. To be more precise, i've an "access denied".
--------------------------------------------------------------

To be more precise i'm going to made some test this afternoon and i come back to put result + smb.conf

Thanks

After some test this is the results (my nas was "nas-indus):

Xcopy = works (xcopy "D:\PFLEX\Gp\*.*" "\\nas-indus\sav_produflex\%JOUR%" /E /C /Y /D)
robocopy doesnt work (robocopy "D:\PFLEX\Gp" "\\nas-indus\sav_produflex\%JOUR%" /MIR /V /NP /TEE /Z /R:00 /W:0 /FFT /XF thumbs.* *.tmp /LOG+:%CD%\log\%JOUR%.txt)

One important thing was it works on a buffalo nas.

this is the config (autoconfig from gui omv) of the share

[sav_produflex]
path = /media/2bdd617a-c961-4359-9210-904938ea3ba0/sav_produflex/
guest ok = yes
guest only = yes
read only = no
browseable = no
inherit acls = yes
inherit permissions = no
ea support = yes
store dos attributes = no
printable = no
create mask = 0755
force create mode = 0644
directory mask = 0755
force directory mode = 0755
hide dot files = yes

This is the configuration of a share that work on buffalo nas

[sav_produflex$]
comment =
path = /mnt/array1/sav_produflex
browsable = yes
printable = no
writable = yes
guest ok = yes
force create mode = 666
force security mode = 666
force directory mode = 777
force directory security mode = 777
csc policy = disable
vfs objects = audit
audit:facility = LOCAL6
audit:priority = INFO
