samba - Jun 2007 - smbclient and mount.cifs having problems accessing Win XP shares

Hi Guys
I am using samba-3.0.10 and Redhat Enterprise 4
on a linux machine called "c4dev".

I have this share on my XP machine called "Spare110-lt"
setup with access to "Everyone" and had Guest account
enabled.

Windows XP IP address : 192.168.1.68
Samba server address : 192.168.1.65

Both machines are in the same workgroup called "IOKO365".
When I try to access shared folder  I got this.

[root@c4dev ~]# smbclient -d 3 -L Spare110-lt -U administrator
lp_load: refreshing parameters
Initialising global parameters
params.c:pm_process() - Processing configuration file
"/etc/samba/smb.conf"

added interface ip=192.168.1.65 bcast=192.168.1.255 nmask=255.255.255.0
Client started (version 3.0.10-1.4E.9).

no luck with cifs as well :

[root@c4dev ~]# mount.cifs //192.168.1.68/SAMBA /mnt/share -o 
user=administrator
Password:
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)


my smb.conf :

#========== Global Settings ==[global]

# workgroup = NT-Domain-Name or Workgroup-Name
   workgroup = IOKO365

# server string is the equivalent of the NT Description field
   server string = Samba Server

# if you want to automatically load your printer list rather
# than setting them up individually then you'll need this
   printcap name = /etc/printcap
   load printers = yes

# this tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/%m.log
# all log information in one file
#   log file = /var/log/samba/smbd.log

# Put a capping on the size of the log files (in Kb).
   max log size = 50

# Security mode. Most people will want user level security. See
# security_level.txt for details.
   security = user

# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents
    encrypt passwords = yes
    smb passwd file = /etc/samba/smbpasswd

# Most people will find that this option gives better performance.
# See speed.txt and the manual pages for details
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.
   dns proxy = no

#=================== Share Definitions ===============   idmap uid =
16777216-33554431
   idmap gid = 16777216-33554431
   template shell = /bin/false
   winbind use default domain = no

[tmp]
   comment = Temporary file space
   path = /tmp
   read only = no
   public = yes


Thanks in advance for any ideas
