Cygwin X display through SSH

[Alan Ning]

Hi there

I have a Window XP laptop running Cygwin's sshd. And I ssh to laptop 
using another XP school machine running Cygwin X. I would like to 
display X graphics (emacs, gvim...) on my school machine.

So in a sense, I am doing this: (i am not sure if I am saying it right)
1. Cygwin X server on school machine
2. sshd on window xp laptop
2. ssh in window xp laptop from school machine
3. run emacs, and have it display on school machine.

I have tried it, but I can't get it to display even with X forwarding. 
Is there something I need to setup for sshd? Does this even work at all?

Thank you

... Alan
