samba - Jul 2007 - Automatic download and execution of logon script

Hello all,

My Windows XP client successfully logon to Samba server.
The Samba server generates automatically a logon script, but my client does
not download it and  run it automatically.
Do I need some special  setup of  my Windows client or something with Samba
server setup is not OK

             .....
             domain master = yes
             domain logons = yes
             socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
             logon script = %U.BAT
             root preexec = /SAMBA/logon/create_logon.pl %U

             path = /SAMBA/logon/
             read only = yes
