testDCOM.py - Simple DCOM test
Usage: testDCOM.py serverName
Attempts to start the Python.Interpreter object on the named machine,
and checks that the object is indeed running remotely.
Requires the named server be configured to run DCOM (using dcomcnfg.exe),
and the Python.Interpreter object installed and registered on that machine.
The Python.Interpreter object must be installed on the local machine,
but no special DCOM configuration should be necessary.
"""
# NOTE: If you configured the object locally using dcomcnfg, you could
# simple use Dispatch rather than DispatchEx.

# Hack to overcome a DCOM limitation. As the Python.Interpreter object
# is probably installed locally as an InProc object, DCOM seems to ignore
# all settings, and use the local object.
