I notice also that there are already directories in Christopher's  path
called 'bin', 'x11', and 'mksnt'.  [ Light bulbs should be appearing in the
in that particular order..... ]

This last one in particular makes me wonder if the Rational tools you have
installed maybe include or are based around the Mortice Kern Systems Unix
toolset.  It's a well-known problem that if you try and run cygwin while
having MKS tools in the \$PATH they can sometimes clash.  I'd want to start a
dos command shell, then remove all the crud and set a minimal \$PATH, and try
again: something like this at the command prompt might work...

---snip---
cd C:\cygwin
PATH C:\WinNT\system32;C:\WinNT;C:\WinNT\system32\Wbem
---snip---

Did you notice that it's the same as his \$LOGONSERVER?  It shouldn't take
that long to look up a hostname when you're logged on directly at the
keyboard of the domain controller.

But of all the environment variables, I think this is the one that's doing
the most damage:

---snip from cygcheck.out---
SHELL = `C:\PROGRA~1\RATIONAL\RATION~1\NUTCROOT\mksnt\sh.exe'
---snip---

Ouch.  So everytime Cygwin bash tries to fork a subprocess, it launches it
using MKS sh.  No wonder it loses!

---snip from cygcheck.out---
TERM = `nutc'
---snip---

Wouldn't have thought cygwin would make much sense of that either.

cheers,
