tramp/plink works with one host, but not another

[Yary H]

Hello all,

I'm running tramp 2.1.7 with "GNU Emacs 22.0.91.1 
(i386-mingw-nt5.1.2600) of 2006-12-03 on W2ONE" (that's NT emacs, on 
Windows XP) - using the plink method.

With one server, I can read directories, read files, write files, all 
the good stuff. Excellent!

Another server, it connects, asks me for password, correctly rejects 
incorrect passwords, but when I enter the correct password, it hangs 
until I hit ^G at the message "Tramp: Found remote shell prompt on 
`yyyy.x-x-x.org'"

Full trace from the session is long so I pasted it here: 
http://www.anope.org/paste2.php?id=ad0d3a6a

side note- my password was in the trace output! I had to manually elide 
the line that says 'tramp-read-passwd: "------"'

Connecting manually, it looks like the setups for the two servers are 
the same, I don't see anything obvious (see end of message). Can anyone 
help me figure this out?

thanks
