daemon COM possible?

I talk about only local server COM, which is EXE.
It starts as a process when a client's request occur.
and destroyed when all clients' request have done.

I want make a COM which is able to be alive even if all clients have done as a "DAEMON".
The COM must be started and ended by explicit order.
Is it possible?

If I understand correctly you have an outof process COM server. Create this as an NT service. You can startup and shut this server down explictly.
