I receive the E_ACCESSDENIED as well when modify the CoInitializeSecurity on
the client (console app). The client-server communication works fine if the
connection point is missing; the client calls the server successfully and I
can debug the server code remotely. But, of course, it fails when sending
notifications back to the client thru the connection point because the Advise
failed previously (or not called if removed that code on the client, just to
be able to debug it remotely).
Should I set up the security manually on the client (console app) machine?

Thanks,
vt
