Old Fashion - DDE Question

Question

hey all, i use old outsource application which create a DDE server, i've built a code that link to that DDE server and Lunch it to other server (worked fine).

now, its can't connect to the DDE server any more, i've check with Excel file on the same Server and its worked fine, i didn't change anything in the code in the server transfer, the code is:

        client = new DdeClient("STAR32", "DDE");
        client.Advise += client_Advise;
        client.Disconnected += client_Disconnected;
        client.Connect();
