[Samba] cannot execute .exe files from a share

Hello, i've seen this error on the mailing list but no solutions.

Problem: No user can execute an .exe file from a group share under any
windows version (wXP til Windows 7).

Permisions: Every user can read, write, delete, etc in that share.
I've chmoded 777 the file but for nothing. The user can copy the .exe
file to another location like desktop and then can execute it (is a
portable aplication) with no problems.

Strange behaviour: The most strange is that if an user copies the .exe
file to their 'home' (his private share on the samba server) then they
CAN run it!.

Another clue: the admin users of the share CAN execute the .exe file

CONFIGUTARION
It's an standalone server joined on a Windows 2003 domain

[global]
        workgroup = HCG
        realm = SOME.ACTIVEDIRECTORY.DOMAIN
        server string = Servidor de Datos
        security = ADS
        map to guest = Bad User
        obey pam restrictions = Yes
        syslog = 0
        log file = /var/log/samba/log.%m
        max log size = 1000
        load printers = No
        printcap name = /dev/null
        disable spoolss = Yes
        domain master = No
        dns proxy = No
        panic action = /usr/share/samba/panic-action %d
        template shell = /bin/bash
        winbind separator = /
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = Yes
        idmap config * : range = 10000-20000
        idmap config * : backend = tdb
        printing = bsd

[homes]
        comment = Directorio personal
        path = /home/%S
        valid users = %S
        force group = users
        read only = No
        create mask = 0600
        directory mask = 0700
        browseable = No

[administracio]
        path = /home/administracio
        valid users = @administracio
        admin users = ds
        read only = No
        create mask = 0660
        directory mask = 0770
        inherit acls = Yes
        inherit owner = Yes
        vfs objects = acl_xattr, full_audit
        full_audit:priority = notice
        full_audit:facility = local7
        full_audit:failure = connect
        full_audit:success = rmdir rename unlink
        full_audit:prefix = Administracio|%u|%m

So an user of @administracio group can execute .exe files in its home
share but NOT the same .exe file in [administracio] share. Except user
'ds' that it is an admin user of the share.

ls -l /home/administracio/program.exe
-rwxrwxrwx 1 administrador administracio 582656 may 23 13:26
/home/administracio/program.exe

ls -l /home
drwxrws--- 56 administrador administracio  4096 may 24 15:01 administracio

(althought chmodig 777 /home/administracio don't work).

Samba version 3.6.3

Thank you!

Try to set the sticky bit for the group on this share.

I'm sure I saw this problem a long time ago - now to see if I can remember
the solution...

Windows security settings?  It identifies the file as being "remote"
(or
possibly "Local-intranet") and Windows is set to not trust remote
files.

Check your Internet Explorer (yes, IE) Security-Settings and if you are 
connecting to the share via the server IP add the IP to the IE trusted 
sites.

Some time ago my users had problems opening Office Files. This was 
caused by the IE-Security settings. The users were connected to the 
share via IP instead of the server's netbios name, so Windows thought 
the file was downloaded from the Internet and blocked it.
