The default Remote Desktop Protocol (RDP) port is 3389.
To clarify, the RDP port is the specific communication channel that your computer uses to "listen" for incoming Remote Desktop connection requests. When you use the Remote Desktop client to connect to another computer, your computer sends a request to port 3389 on the target machine (unless it's been configured differently).
While 3389 is the default, it's important to know that:
- The RDP port can be changed. For security reasons, some administrators change the default RDP port to a different number to help prevent automated attacks that specifically target port 3389.
- You may need to know the specific RDP port if it's not the default. If the target computer's RDP port has been changed from 3389, you'll need to specify the custom port when connecting through the Remote Desktop client. You can do this by adding the port number to the end of the IP address or hostname, separated by a colon (e.g.,
192.168.1.100:3390). - Firewall configuration is crucial. Regardless of whether you're using the default or a custom RDP port, the firewall on the target computer must be configured to allow incoming connections on that port. Otherwise, you won't be able to connect.
In summary, while your default RDP port is likely 3389, it's crucial to confirm that the target machine is using this port and that the firewall is correctly configured. If you encounter connection problems, the RDP port number and firewall settings are good places to start troubleshooting.
