Problem with getting events from a DCOM server

[Haegi Kim]

I have a COM server which inherits ConnectableServer class and exposes
an interface. It works very well with firing events in InProc Server,
but doesn't in Local/Remote Server. The problem seems to be raised
from QueryInterface failure, since attempting to <A
SimpleConnection>.Connect fails saying that the server doesn't support
the interface requested. What do I miss? Please give me an advice.
Thanks in advance.
