XDMCP

[David Calkins]

I'm trying to connect up to a machine at work using XDMCP.  My home machine 
is Win2k + Cygwin + XFree86.  I made sure to use the cygwin setup program 
to get the latest packages.  I'm using the -query option to do this, i.e.
XWin -depth 32 -engine 4 -fullscreen -refresh 85 -screen 0 1024 768 -query 
$remotehost
I get the login screen, enter my username and password and attempt to 
login.  For some reason, I just get bounced back to the login screen 
again.  I've been unable to get this to work.

Any ideas as to what could cause this?
