problems with remote display

[Claudio Tamietto]

I'm sorry for my poor english but i don't kwown it very well .I'm a programmer
and I'd like unix but unfortunately j have to work on windows paltform so i have
installed cygwin on my windows 2000 workstation. Actualy i have the latest
version of cygwin (1.3.12-1) and Xwin (4.2.0-7) installed. If i run the X-server
locally with the command startx from a bash shell all seems function correctly
but if  i try to run a remote dislplay  on  aHP_UX unix server whit the command
startx -- -query ip-of-remote-machine the following message appear on the
console :

..
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Here follow the content of the file Xwin.log found in /tmp
