Unable to share win folder in AIX

Hi,
Iam unable to share WInXp folder in AIX, i configured samba, its working fine, i am able to access win folder from AIX by using samba but unbale to access AIX folder from Windows.

bash-3.00# mount -v cifs -n Win_IP/Win_username/Win_passwd /Win_Folder /AIX-folder

Result:
There was an error connecting the share or the server.
Make sure the lsdev command shows that device nsmb0 is in
the Available state. Also make sure that the share name,
user name and password are accurate.

nsmb0
nsmb0 Available N/A

please give me the solution.

and
----

mount -v cifs -n Win_machine/user_name/password /Win_share_folder /AIX-Share_folder

and i am getting below error.

-318 cifs is not a known vfs type for object /test.

Do you have these filesets installed?

hostname:/:$ lslpp -L | grep -i cifs
  bos.cifs_fs.rte            7.1.0.0    C     F    Runtime for SMBFS
  bos.cifs_fs.smit           7.1.0.0    C     F    SMIT Interface for SMBFS
hostname:/:$

Also, samba only lets you mount the share itself. You cannot map subdirectories in Windows share. If they share on the Windows box is "Win_share_folder", then that is what you have to mount. I map Windows shares on my AIX boxes and the syntax you are using is the same that I use. Here is the example command I modify when mapping Windows shares.

mount -v cifs -n rmt_hostname/rmt_user/rmte_password /rmt_share /mnt/windows

Also, if the Windows user account is a domain account the "-o wrkgrp=domain" has to be specified in the command. If you are authenticating with a local Windows account (versus a domain account), the option is not required.
