Just like the error message says: you are not specifying which display
to connect to.
The "--ssh=" switch only specifies the ssh command line to use when
using ssh for transport.

Unless you have a local unix display running on Windows via cygwin, this
command line is just as wrong as the previous one.
(and even if you did, I'm not even sure that would work as cygwin is not
supported)

I'll try to improve the error message, but this will remain an error.

That looks more correct: now you are telling xpra where the server is
*and* that you want an ssh connection to it. (assuming "server-host"
resolves or that you use its IP)

Does it work from a Linux client?
Are you sure that your username is indentical on both hosts? (if not,
add username at host or specify it in the plink command line)

Try connecting to your server with a simple terminal (putty.exe on win32
or a plain terminal on Linux), and if you can connect to the server with
that same command line, then verify that there is an xpra server to
connect to. ("xpra list" should be enough to see it)
