In order for one machine to behave as a client to a server running on
another machine, the server machine must have the client machine
listed in its `hosts that are permitted to use me' list (accessed
through the `xhost' command).  In your case, it seems running:

consult1.its.rpi.edu% xhost risk.its.rpi.edu consult1.its.rpi.edu

will work.  I know 18.53 and 18.52 work with X both locally and
remotely since I am using it now.  If this does not solve your problem
you may give me a call or send me mail.
