Everything You Should Know About Port 135

Being a network administrator or a security expert, you must be wondering about Port 135. This port is a vital link for important functions in Windows-based systems within a network. Its significance lies in enabling different parts of a computer to communicate smoothly. Additionally, it plays a necessary role in strengthening networks and ensuring the safety and reliability of Windows systems.

In this article, we'll explore what TCP Port 135 is used for and will explain its connection to Remote Procedure Call (RPC). We will also outline steps to open and close this port on your computer smoothly. So, start reading this guide to learn why Port 135 is so important and why knowing about it matters significantly for those involved in managing networks and ensuring security.

Part 1. Understanding TCP Port 135: A Quick Overview

TCP, or Transmission Control Protocol, acts as a messenger to help computers communicate with each other over the internet. However, to ensure that these messages get to the intended PCs, they use ports that can also be referred to as virtual meeting points on the internet. Each port has a number, and they help identify different types of information and applications on devices.

Now, when it comes to the TCP Port 135, it works as a guide for computers. Besides, it is also known as the RPC Endpoint Mapper service. It is a very helpful service that helps other computers to recognize what's available on a specific computer and where to find it. Plus, Port 135 is commonly used for remote access and management, meaning you can connect to another computer and see its services or programs.

So, Port 135 is, however, a key point to maintain client-server relations, especially in the Windows OS. Moreover, Port 135 is closely connected with RPC (Remote Procedure Call) and DCOM (Distributed Component Object Model). RPC lets you run actions on your computer from somewhere else on the network, while DCOM helps different programs on a Windows computer communicate with each other.

Part 2. How to Manage Port 135 By Opening and Closing It?

Understanding how to control data flow by managing ports in your network is necessary for keeping it secure. TCP 135 Port is especially important for communication in Windows systems. You'll need to adjust your firewall settings to manage this port. However, the steps can differ depending on your operating system and firewall software.

However, opening or closing Port 135 is not simple and requires careful consideration based on your system's needs and security requirements. It can greatly impact how your system works and its safety. Let's discuss the general steps for opening and closing TCP Port 135. These steps will help you navigate port management in your network effectively.

1. Opening Port TCP 135

First, we will start discussing how to open or create a new TCP Port 135 on your system:

Step 1: At the start, navigate the "Control Panel," followed by the "System and Security" to view different options. From there, locate and select the "Windows Defender Firewall" feature.

Step 2: Once in Windows Defender Firewall, click "Advanced Settings" on the left-hand side to access more detailed configuration options. Afterward, find and click on “Inbound Rules” within the new window, and then proceed by selecting the “New Rule" option on the right-hand side. Then, select the "Port" option as the rule type you want to generate when asked, and afterward, click the "Next" button to proceed.

Step 3: In the next step, choose "TCP" as a rule and enter "135" in the field labeled "Specific Local Ports.” Following this, proceed by clicking “Next” to move to the next configuration step.

Step 4: Now, choose "Allow the connection" and click "Next" to continue configuring the rule. Moving on, select the network types (Private, Public, Domain) to which this rule should apply and click “Next” to proceed further.

Step 5: Provide a “Name” for the rule and, if you want, add an optional “Description.” Finally, click the “Finish” button to complete the process of creating the new rule.

2. Closing Port 135

After you have created a new port using the new rule, let's learn about the steps regarding how to close it. This, however, makes sure that your computer is marked safe when the TCP Port 135 is not in use:

Step 1: Start by heading to the "Control Panel" and then click "System and Security." Now, look for the “Windows Defender Firewall” option and select it. Afterward, inside the Windows Defender Firewall, click "Advanced Settings," located on the left side, to access detailed setup options.

Step 2: In the new window, locate and click "Inbound Rules." Next, look for the specific rule you might have set recently or permits Port 135. Finally, right-click on the rule allowing Port 135 and select the "Delete" option by right-clicking it to remove it from the inbound rules list.

Part 3. How Much Safer is Port 135?

Port 135 on your computer is used by a service called "DCOM Service Control Manager" from Microsoft. This port lets other devices know where to find DCOM services on your computer. However, it can be risky if exposed to the internet. Simply put, if TCP 135 is left open, hackers can access your computer. Using this port, some tools can find and match up services on your computer.

So, it makes it highly important to keep this port closed. Moreover, if you need to open Port 135, ensure strong security measures are in place. This helps limit access to authorized users only and keeps your system safe. So, always be cautious when dealing with TCP Port 135 to protect your computer from potential risks.
