Furthermore, Kim is right, and I have to read more carefully
when replying. You never registered your object in the ROT,
that's why you can't find it there. ROT is not related to the
table of registered class objects (which you can't query
through any documented APIs, other than CoGetClassObject
and CoCreateInstance[Ex]). ROT contains objects, not class
objects.

works because I wrote the server as well as the client, and I should not
have to do that; it should be easy to determine whether a class is in the
ROT.  It certainly appears that GetActiveObject()  is returning an erroneous
result.
