samba - Oct 2009 - NT_STATUS_LOGON_FAILURE

I am running Fedora 11 and trying to set up Samba. I've succeeded in setting
up the network printer.
I am able to go only to this stage: Place--> Network--> Windows Network

Do you have any suggestion? Here is what I get when I do troubleshoot.


I get the message in the tile when I do:

$ smbclient -L 192.168.0.144
Enter smarty's password:
session setup failed: NT_STATUS_LOGON_FAILURE

* 192.168.0.144 is the ip address of the Windows Vista box

The essential info in '/etc/samba/smb.conf ' is as below:

[root at localhost ~]# testparm -s /etc/samba/smb.conf
