samba - Dec 2007 - Not able to see files on Win XP (service pack 2)

Hello friends,

I'm a newbie on this list and this is my first message here. I'm not new
to
Samba.
I've been using the standard stuff that comes with Fedora and RH distros. I
mostly
do configurations through the GUI and haven't really edited the
smb.confmanually,
till now that is !

During the course of my work, I was recently faced with the need to
integrate Samba
into our working software. This is a small Linux based ADSL modem/router
running a
2.6 kernel. I need the ability to share some flash file-system folders and a
USB-
attached storage device over the network. The obvious choice is Samba. So, I
downloaded
Samba 3.0.27, configured and built it on a native host first and tested it
there
to work fine. But the size was too big to fit on the target platform. So, I
went
back to 2.0.0 version. I integrated it with our software, tweaked and was
successfully
able to run it. I did use the default config file and added my share info.

I use a share [tmp] which is a directory on the FFS and has some files. When
I access
this share on my Windows XP, from the Start->Run (\\192.168.1.1\tmp), the
explorer
window opens, But -
1) I can't see any files.
2) If I try to create a new folder or a text file, I get an error but when I
go back
to my platform I can see that a folder or empty file was created there.

On my native linux, I see the same problems !!! (and 3.0.27 was fine)

My smb.conf is pasted below this mail.

I've already tried a lot of configuration options after going through
several such user
experiences over the web without success.Any suggestions as to what the
problem could be
or how I can achieve what I'm trying to would be really appreciated.

Thanks,
Kunal
