My problem is solved now. Thanks for your reaction. MauriceMH

I am new in COM programming so I have a question that is maybe very simple for you, but I do not know the answer. My client and server applications are running on two different PC's, so I have a remote connection. I want to implement the client in such a way that the user can change the name of the PC where the server is running. I want this to be flexible for future changes if the server has to be installed on another PC. Can someone explain me how to solve this? Do you have an URL where I can find an example with the solution for my problem. Thanks. MauriceMG
