Controling LabView-Exe over a network

Hello out there,

I'm working with LabView 5.1 on NT 4.0 machines in a TCP/IP network.
I'm trying to write a Visual C++ 6.0 application which controls a LabView-Exe
on a remote server.
The Exe was build with the ActiveX-Server enabled.

The application works, starts and controls LabView on the _local_ machine.
To make it work over the network I used the racmgr32.exe and autmgr32.exe
tools shipped with Visual C++.
This configuration won't work.

My Question:
Do I have to make a connection using DCOM or is it possible to use remote-automation
with the racmgr32 + autmgr32 tools ?
Has anybody experience in doing so or can give me a link to an example (including
DCOM) ?

Thanks for any help.
Regards,
Ralf Erdmann

Ralf,

In case you haven't seen it, there's a good example of the DCOM approach to this in the
Example Programs Database on the NI site:

Unfortunately, I don't have any insight on the Visual C++ utility executables you are
using.
