The connections are being stored via monikers in the ROT. Despite the

crucial), all the DLLs unload cleanly when I close the Explorer
window! How can this happen? Shouldn't the outstanding references
to the connection COM objects should lock the server?

You said what you have is a "connection to a remote server". I assumed
that you literally have an interface pointer to an object implemented in
some out-of-proc server (possibly running on a different machine). In
which case, it's that server that's locked by storing its pointer in the
ROT, not your DLL (which acts as a client, not as a server).

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
