Do you need multiple servers? Is this an out-of-process server? The server isn't on a remote machine is it? Did you write them both?
You could call: CoRegisterClassObject[^], which associates the registered class object with the apartment of the caller. You can then obtain another pointer to the running object by using a Class Moniker[^].
Explanation from Don Box: "A process becomes the server process for a particular class by explicitly registering itself with the COM Service Control Manager (SCM). Upon registering with the SCM, any activation requests for the class that require out-of-process activation will be dispatched to the registered server process."
"The SCM is the central rendezvous point for all activation requests on a particular machine. The services of the SCM are exposed to programs as high-level moniker types (Monikers are COM locator objects that hide the details of an activation or binding algorithm), and as low-level API functions, all of which are implemented in what the Component Object Model Specification calls the COM library."
You might also read up on the: IRunningObjectTable Interface[^]. The Running Object Table (ROT) is a facility of the SCM that maps arbitrary monikers onto running instances on the local host machine.
If this isn't what you need, you could probably set up a policy by adding a registry key/value to your CLSID key, and read that specific key with all subsequent server instance activations.

By the way, this line from your post:
How is the IUnknown getting attached to a certain process? If I could figure that out, then I think I could call CoCreateInstance to get the uninitialized IUnkown, then do the missing piece to initialize the IUnkown and then I can query for the IDispatch.


...doesn't make alot of sense. If you can get a copy of Essential COM. by Don Box, I would recommend it highly. This book will give you a basic understanding of COM, and why COM does what it does.
