I heard that the Midas app uses the DCOM to set the trouble, the firewall is also a problem, and the connection is changed to SocketConnection.
When setting the SOCKETCONNECTION server, prompts the "Socket Error, the Target Machine Positive Reject", and the optional server cannot be displayed. I have asked many people in QQ, and I finally found the "BCB program design". It turns out that the server did not launch Scktsrvr.exe.
After starting SCKTSRVR.EXE, try again, everything is normal, it seems that the next question is still looking at himself.
