[Samba] Creating private shares

[Devanesan]

Hi,

I am a beginner in Samba. I want to create private shares in the 
server(RedHat Linux) for individual users who are using Windows. I have 
placed the script listed below in the file "/etc/smb.conf"
and restarted samba. But the private share (example z:) is not appearing 
automatically when a
user logs on to his machine, while it is working manually when I click 
"NETLOGON.BAT".
**************************
logon script = NETLOGON.BAT

[netlogon]
comment = Network Logon Service
path = /usr/local/samba/netlogon
guest ok = yes
writable = no
share modes = no

[samba]
comment = Login traking share
path = /usr/local/samba
root preexec = /usr/local/bin/netlogon.sh %u
root postexec = /usr/local/bin/netlogoff.sh %u
*****************
Kindly guide me where I am going wrong and please point me the exact steps 
that
needs to be followed.
Thanks in advance.

Regards
Devanesan.
