    Hi, Harry,

    I know of only one case when you will see 0x80004015 returned from
    CoRegisterClassObject( ). This happens when you try to register a CLSID that
    has an APPID with RunAs account different from your server's identity. I
    don't know whether this is what happens in your case, but it's only
    explanation I have.

    Now, however, I can explain why you had success in Win2000 and you regressed
    in Win2003:

    In Win2000: any process can register ANY CLSID for a server if it is 1.
    service 2. running now. COM doesn't block the registration in this case.
    This is inherently a bug.

    In Win2003: the bug is fixed. COM blocks incorrect registration ALWAYS and
    you see the error.

    Hope this helps,
    Dmitrii
