Here's some meta-help:

paramiko seems to be actively maintained and has a mailing list -- see -- consider asking on
that list.

Not only is paramiko open source but also you have the source code on
your machine already -- consider looking at C:\Python23\lib\paramiko
\ and see if you can nut out what it is complaining about.
Even if you can't, the experience may help you to better answer
questions from the maintainer, who may well not have a Windows 2003
server box upon which to replicate the problem.
