Remote DCOM on WinCE 6.0

The company I work for is implementing control of a piece of equipment on an
ARM-based board running Windows CE 6.0. The board is to be controlled from a
PC running XP Embedded. We will use DCOM. We applied the DCOM .msi to
Platform Builder to incorporate DCOM remoting in CE 6.0. The network is
closed, so we do not have to be worried about security issues.

We've been struggling for two weeks now to get DCOM remoting to work, but it
does not yet. We've created a demo application on WinCE that creates a COM
server inproc, but outproc just does not work. Below, you see some logging.
Whatever we change, we just keep getting an 80070005 upon calling CoCreate().

My question is whether there is some kind of readme on how to set up remote
DCOM in CE 6.0 ?

I understand from blogs and discussion groups there's a lot to set up to get
remote DCOM to work in CE6.0. In microsoft.public.windowsce.embedded, on 8th
July this year, John Spaith stated there's an example available for CE5.0 to
add numbers across distributed machines. Is such an example available for CE
6.0 too?

Any help will be greatly appreciated.
