Hi

In May 1999 MSJ, Don Box writes in ur column "House of COM":
 
"Note that as long as a proxy is present, the object and client
independently determine whether they will use blocking or non-blocking
invocation. Also note that in the absence of a proxy, as long as the
object supports ICallFactory as described earlier, the client can issue
non-blocking calls directly against the object."

In my case, the server does not support ICallFactory. If the client
issues parallel simultaneous asynchronous calls to the COM object from
the same thread then most of these calls fail with RPC error (even if
separate call objects r used for each call). However parallel calls from
different threads succeed. Can this be due to the fact that the server
has not implemented ICallFactory interface? I earlier thought that
client's ability to do asynchronous operations (parallel calls
including) has nothing to do with server object's implementation
(whether or not ICallFactory has been implemented).

Any comments?

Thanks
