I have used Cygwin/X on two computer in my office and it works
with no problems. There are several users who cannot use the

ERROR: Cannot open X display. Check display name/server
access authorization.

This is the steps that I use in my office to run Cygwin/X:
1. Execute “startxwin.bat”.
2. On the window that opens I type: xhost +
hostname.temple.edu. Then I type: ssh –X

3. I type my password and get in with no problem. Then I
type: setenv DISPLAY myipaddress:0.0.
This is wrong, if you used "ssh -X" then DISPLAY is already set (by ssh) and it
has a different value, usually localhost:10.0 for the first connection.
The idea is that ssh will tunnel the X connection through itself (thus
localhost) and it uses a configurable display number (the 10.0).
The reason it works from some computers and not from others is that even if the
X server exists at myipaddress:0.0 it could be blocked by any firewall between
computers; the ssh tunnel is the way to avoid being blocked.

Try skipping the "setenv DISPLAY myipaddress:0.0" step.
