SOLIDWORKS PDM – Test Port Communication using Windows Telnet feature

Article by GoEngineer on Jul 30, 2020

Overview

Windows Server, Windows 7, and Windows 8 have built-in firewalls activated by default. These can restrict network access to applications requiring connections over the TCP/IP interface. You can test port communication by using Windows Telnet client feature in a command prompt to check communication is working properly. For step-by-step instructions on opening ports for client and server communication, please see the section ‘Opening ports for Client/Server Communication’ in the SOLIDWORKS PDM Installation Guide. This section is located in Chapter 5 – Installing SOLIDWORKS PDM. This table summarizes the ports that must be reachable. You open the firewall ports on the listening/receiving side.

6. If the telnet failed try substituting the with the IP address of the server.
7. If the telnet still fails there is a TCP/IP problem between the client and the server and it should be investigated by the network administrator. It is possible that a firewall could be blocking communication on that specific port.
