Cannot connect with tramp when ssh works

[Harry Putnam]

Setup:  Emacs-24 compiles with mingw
        Running on windows 7
        tramp version 2.2.1-pre
        plink version 0.60

I can connect to all machines on my lan but 1.  I use plink since ssh
  attempts from emacs have failed long ago.

  /plink:address@hidden:/

That works on all but 1.

That machine is a netbook running windows 7 starter.

On that one I get prompted for a password, It appears to be accepted
and tells me I'm connecting to HOST by way of plink, then the little
timer bar spins and spins 

I can connect to that same machine with ssh from a terminal anywhere
on the lan with no problem.

Plink fails in emacs/tramp and from a terminal.

When I try using the plink utility from a terminal to connect to the
problem machine, the password is rejected over and over.

First here is the ssh output from a terminal on the lan:

ssh address@hidden "ls pym.txt"
  address@hidden's password: xxxxxxx <RET> 
  pym.txt

I set (setq debug-on-quit t) and attempted a connection with
 emacs/tramp:
    /plink:address@hidden:/

C-g

and here is the backtrace (I've replaced
the byte code with [...]):
