Network icon in Fedora Core 3-gnome

Fedora Core 3 comes with gnome and has a network icon in the desktop
that allows you to browse your network, similar to windows.
I have samba activated in my laptop and everything works fine from the
command line, but If I use the network icon I see the machines in my
network but I can not access them. I can access them using directly
the IP address but not the netbios name, so it's a name resolution
problem. I have a wins server in my LAN and the laptop acts as a wins
client, the smb.conf is properly configured, in fact everything works
from the shell, but it seems that nautilus (from gnome) is not reading
the /etc/samba/smb.conf, or should I configure gnome again to use the
wins server ?

I've tried to use the gconf utility to configure this wins server in
gnome, because it has a key called smb where you can specify your
workgroup name, but I don't know if I have to add another key to
specify a wins server, I have tried with "wins server=ip address" but
it says is not a valid key.


So any idea ?

Thanks
