Unable to get XDMCP to work after cygwin apgrade

["Richard Toy" <THETOYS at hetnet dot nl>]

Hi

I recently upgraded my Cygwin installation on my XP SP1 machine.  I used
setup to retrieve and
then to completely reinstall but once I had finished I could no longer
get my Mandrake 9.0 desktop
to appear.  It is still displayed if I use an older Cygwin installation
on a laptop that I have 
(also XP SP1) but it will not work with the new installation.

The only line I change in the standard startwin.bat file is: -

start XWin -screen 0 1024 768 -ac -from pluto -query moon

This is the contents of the XWin.log file after a failed attempt: -

Fatal server error:
XDMCP fatal error: Session failed Session 40592002 failed for display

Anybody got any answers?

As I have already said, It worked before the upgrade and the upgrade was
a *complete* install
After the old C:\Cygwin directory had been removed.

Thanks for any help
Richard
