Re: [TCLUG:8991] Remote X from Windows

[Peter Lukas <peter@math.umn.edu>]

You should already be broadcasting XDMCP.  Check
/usr/X11/lib/X11/xdm/Xaccess for details, but you'll still probably want
to specify the IP address of your NT box rather than the "*" that goes in
by default.  Also, this can vary depending on which (x/g/k)dm manager you
run.  You'll have to consult to docs for whichever one suits your fancy.
