If the program does not respond to requests or the client application does not receive data from the server, the port of the program or service is blocked by Windows Firewall. Registration of rejected packets will help you identify blocked ports and applications, Netsh Helper will help you tune your firewall configuration, and adjusting Group Policy settings will troubleshoot program execution problems.
