samba - Oct 2010 - Upgrade problem

Hi,
I am working on the upgrade from 3.0.9-1.3E.14.3 to 3.5.2.  Currently, the
installation and smbd daemons running.  I did not make any changes on smb.conf
or smbpasswd.  The new version shows up when using smbd -V.  However, it still
shows the old version when I tried to map a drive on window:

+homes on 'Samba 3.0.9-1.3E.14.3'  (O:)

It shows all contents there.
Any ideas?

Thanks.
