export display from linux to windows

Hi Experts,

I was trying to export display from my suse linux desktop(a.b.c.d) to windows pc.
Installed Xming, in the additional parameters added option -ac.
on the linux, I entered
export DISPLAY=10.122.94.61:0.0
and when I run xclock,
# xclock
Xlib: connection to "10.122.94.61:0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: 10.122.94.61:0.0

On windows I checked out xming log and it says
