no connection to samba shares

When I try to browse samba shares I am stuck with this:

$ smbclient //madura/home/data -U shareaccess
Enter shareaccess's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.6-86.el6_1.4]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME

I can ping client from host and host from client smbd is running on the
remote host with the -D option

testparm gave no errors

my smb.conf looks like this:

[global]
workgroup = WORKGROUP
server string = samba
security = user
passdb backend = tdbsam
load printers = no

[data]
comment = data directory
path = /home/data
writeable = yes
public = no

any help greatly appreciated!

First of all you should be doing a test with just

smbclient -L madura

and just hit <CR> at the password prompt.

If that does not work then it means that your SAMBA server
is not accessible from the current host.

Just because you can ping it, does not give any indication
if there is a firewall blocking the port 139 (netbios-ssn)
needed for SAMBA to work properly.

Have a look in /var/log/samba to see, after the above tests,
if a log file log.[IP_ADDRESS_OF_CLIENT_MACHINE] has been
created.

If not, then probably your client machine just cannot connect for
some reason to the SAMBA server, and if it does exist, have a look
inside at the messages. Also check in the log.nmbd file to
see if there was a client request from the client machine.
