It will be interesting to hear how you get on ...
Yo may find that you will have to trawl though the MSDN site on-line and
hope you hit it lucky with some searches.
Note that in the service setup you can have the service run as a particular
user, and allow it to interact with the desktop. Note that the "SYSTEM"
account is rather special in what it can/can't do.
eg When I run IIS in process (rather than as a service) for debugging under
Delphi you have to have certain privileges enabled - else it's no go.

Hi Miles,
Security was my thought as well. It is running as "SYSTEM" with interaction
with desktop enabled so I was hoping this may would allow other applications
to interact with it.
Unfortunately running the Service in the context of the user logged in still
resulted in the a new COM server being started.
Do you know where I can start looking to find the interface that would allow
the COM object to run as a particular user?
Thanks,
David.

Sounds like a security issue.
Does the service run as a particular user?
If not it probably runs as "SYSTEM" to which you as a user do not have
access when run as a application. You may get it work by running your
service as a particular user, or by granting the appropriate access rights
to the user (eg Act as part of the Operating System).
There might be some way to get your COM object to run as a particular user
no matter who tries to access it. In my trawling through the COM/MTS/COM+
interfaces I think I saw something that allows you to do this (Of course
this assumes my guess about security is right in the first place).
Myles.

Subject: [DUG]: COM server created by a service
Hi,
I have a COM out of process server (exe) that is being created by a service
so the COM server run's all the time. The service is interactive. I have
another application that creates this COM server.
When the application creates this COM server a new instance of the COM
server is started (indicated by a new form being displayed). If this COM
server is started by a non-service application and then created within the
other application the same COM server is used.
How can I get the application to access the existing COM server that was
created by the service as it does when created by a non-service application?
