I create MMC snapin using C#. Everything works fine until I try to access any MMC COM objects from another thread. I get exception which says:
An unhandled exception of type 'System.InvalidCastException' occurred in computernode.dll
Additional information: QueryInterface for interface IConsole2 failed.
What can be done about that?
may be that's the threading model issue.
what are you casting ? by the way...

I think you forgot the convert a type from one to another... try to find the line where it gives the error and fix the type casting there :)
since he wrote 'from a thread' so i gave idea of - checking theading model. type casting would also be a problem.
check that plz. and return with your answer.

Well, actually, it was the first thing I've checked about this bug :) The problem is that it works when it is in the main thread, the same code doesn't want to work in another thread.
Euhm yeah, well I will try that too :D, I post a message here when I have results (good or bad).
VALE rA
did you got the solution around.
I would be interested in knowing ur problem
