I am sorry you don't see that. It is clear to me so I did not want to write
a lengthy explanation. However perhaps a little clarification will help.

Most anything that can be done using a RPC can be done using DCOM. I am sure
that for more complicated and/or advanced requirements, using a RPC directly
might provide a solution that cannot be done using DCOM or that has some
advantage, but for the relevant requirement DCOM would be a higher-level
solution that VB would make much easier to implement.

An even easier solution might be WMI. The WMI WIN32_Process class has a
Create method that appears to be able to create a process in another system.
It is likely I can do what I need to do with just a few lines of code.

The following is a question I posted a question in another newsgroup and an
answer to my question.
