Give a servcie DCOM permissions

[fluppe]

Hello,
i have a service written in C++. everything works fine so far, if i run it under a specific account.
What i intend however is to grant the servcie special DCOM rights. Therefore i need to find it within the DCOM configuratioon settings pane in the Computer administration ... but i need to register the service as a DCOM component with CLSID and so on, right?

I wonder how to do that and if this is possible anyway.
I could not find anything really helpful on this topic, because it seems all refs i found start at a point far beyond my knowledge on DCOM.

Thanks a lot in advance for any hint
