Hi, I have a big problem. I am using a client/server application. The client is a WinNt Workstation and the Server is a W2k-Server. When the client tries to create the remote ComObject, the package of the com+ on the server hangs and all other client working with the same application on the W2K-Server hang too. Furthermore I can´t shut down the package. I changed the dcom default protocol of the client to tcp/ip instead of udp, but it does not work, too. W2k-Professional Clients do not have the problem. What can I do???
