RDP is a proprietary protocol developed by Microsoft, and is used to provide a graphical means of connecting to a networked computer. It is typically used by administrators to remotely manage servers, and by users to access their own desktops. RDP is based on the T.125 protocol and uses port 3389 by default. Let’s dig in to know more.
What Is RDP (Remote Desktop Protocol) Port?
RDP port is the port on a computer where Remote Desktop Services (RDS) can be accessed. The port can be configured to accept connections on a specific port number or on a random port. These are used by the Remote Desktop Protocol. By default, RDP uses port 3389. RDP port is needed for Windows systems that are configured to allow remote desktop access. This port allows remote users to connect to the system using the Remote Desktop Protocol (RDP).

Method 3: Connecting to a Remote Desktop Using a Custom RDP Port
It is possible to connect to a remote desktop using a non-standard RDP port. This is a way to make the RDP connection less obvious to hackers and other intruders. To access the remote desktop using a non-standard port, you must first configure the server to use a non-standard port. This is done by changing the port number in the RDP settings of the server.
Once the server is configured to use a non-standard port, you can connect to the remote desktop using that port. To do this, you will need to use the IP address of the server, followed by a colon, and then the port number. For example, if the server is using port 3390, you would connect to it using the following address: 192.168.1.100:3390
You can then connect to the remote desktop using the same credentials that you would use to connect to the server using the standard RDP port.
Conclusion
Well, that’s it for this blog. I hope you found it helpful. To summarize, Remote Desktop Protocol (RDP) is a remote access protocol that enables users to access their computer from a remote location.
