Simple Question

[Administrator]

Hi,
I'm new to linux and samba but I desperately need to get this thing
working so I'd appreciate any help anyone could give me.

My problem is this: 
Samba successfully registers itself with my WINS server (a Windows 2000
domain controller) and appears in the appropriate location in "Network
Neighborhood." However, I am unable to browse the shares provided by the
samba server. (IE, if the server name is "smbserver", then SMBSERVER is
present network neighborhoos but I am unable to browse into the server
itself to view its shares) I receive the message: "\\Smbserver
<file://\\Smbserver> is not
accessible \n The account is not authorized to log in from this
station."

My smb.conf file looks something like this: 
; Riovia I.S., 16 October 2001

[global]
log file = /var/log/samba-log.%m
lock directory = /var/lock/samba
workgroup = Protaxemployees
mangle case = yes
case sensitive = no
default case = lower
wins server = 192.168.100.28
name resolve order = wins hosts bcast 
guest account = riovia
; Every user will have a home directory
;[homes]
; comment = Home Directories
; browseable = no
; read only = no
; create mode = 700

; /data/shared is a folder that every user can use
[shared]
comment = Shared Folder
path = /data/shared
writable = yes
public = yes
create mode = 666


This was actually created by two people who dont really know what
they're doing so, any inut would be more than welcome. Its not that
important that we serve domain logins just yet. ANY log in is good
enough for me at the moment.

I would really (REALLY) appreciate any help anyone cold provide.
