Samba Posix Locking On Windows Xp Sp3
  • Sympotom: on Windows XP SP3 clients, when open files with MS Word or Excel on an SAMBA share(NFS export mounted on SAMBA server, then shared with SAMBA), the files can only be opened with read-only mode.
  • Solution:
    • add
      • posix locking = no
    • in the share section of the /etc/samba/smb.conf.
    • restart Samba server:
      • /etc/init.d/samba restart
