Strange Question: Xfree86 on Terminal Services(RDP)

We have students that logon to a Terminal Server and sometimes want to use
unix resources.  We have been using X-Win32 and I thought I would give
Xfree86 a try.  From my computer cygwin-Xfree86 works fine.  From the
Terminal Server using cygwin-Xfree86 we experience no stability and many

The XWinrl.log files did not have anything suspect, however, I did find a
stack dump (below).  This happens whether I am using the Test79 Server or
the latest Standard Xwin.exe Server.

Does anyone have an idea of how to increase the stability of cygwin-Xfree86
in a Terminal Service session.
