I am not able to open any Window's share on my RH 9.0 machine. 

Versions of related components:

nautilus-2.4.x (latest HEAD)	
gnome-vfs-extras-0.9.11
samba-3.0

I did the following:

a) Start nautilus and type smb://m3-gnome-naren/
b) Nautilus throws up username/password dialog. 

After giving correct username/password, it throws up an error dialog
"You do not have the permissions necessary to view the contents of
"smb://m3-gnome-anju"."

And I get the following messages on the commandline
auth_fn called: server: m3-gnome-anju share: IPC$ wgroup WORKGROUP
UNLOCK
do_is_local(): smb://m3-gnome-anju
do_is_local(): smb://m3-gnome-anju
do_is_local(): smb://m3-gnome-anju
do_is_local(): smb://m3-gnome-anju
do_is_local(): smb://m3-gnome-anju

Is there any extra samba configuration I need to do so that I can access
the shares.

Right now, I am just adding the correct work groupname to
/etc/samba/smb.conf file, which is the smb default configuration file.

Note:
1. I can mount the Window's share ("naren") from commandline to /mnt
  mount -t smbfs -o username=naren //m3-gnome-naren/naren /mnt

2. I could see the all the shares on the machine "m3-gnome-naren" using
smbclient.
 smbclient -L //m3-gnome-naren -U=naren

3. Also I could user the smbclient prompt to access the shared files.
  smbclient \\\\m3-gnome-anju\\naren -U=naren
