X windows display problem

[Meredith Finkelstein]

Thanks to everyone for their help. 

However I am still not getting it to work... 
 when i echo my DISPLAY variable in cygwin it  gives me 172.0.0.1 - the loop 
back (or whatever the proper term is) - using this value remote xwindows does 
not work.

when i change the display to the actual client ip number and ssh - remote 
xwindows still does not work. 

when i ssh and am on the remote host, and i echo the DISPLAY i get nothing. 
but i thought this was normal since i'm using the X flag with ssh.  Anyway 
when i set export the display=<localhost>:0.0 & then run xeyes
then i get the following message
Xlib: connection to "<localhost>:0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: <localhost>:0.0
(nb - it puts my ip number instead of localhost)
thanks a lot & any other suggestions would be greatly appreciated
