samba - Apr 2003 - Windows XP + SSH tunnelling

Hi,

I need to be able to access a Samba box behind a SSH box from a Windows 
XP box on a home network.

To cut a long story short, the SSH server box can mount shares on the 
Samba box, telnetting to port 139 on the Win XP box does indeed connect 
to port 139 on the Samba box, but the command "NET VIEW \\127.0.0.1" 
gives "System Error 53".

Any ideas?
