How to check if an instance still exists?

[Jonathan de Halleux]

Here's what I do: I create an instance of a server using CoCreateInstance and the interface. I check that everything went good using the return value and continue on. Here is the problem: Later on, the server is closed (ex. because no more license is available) but I don't know to get notified by that. The question: How can I check that the server is still alive ?
