Having to switch between multiple desktop client windows to access them remotely is highly time-consuming and leads to a cluttered desktop. But you can simply ditch the frustration by using RDCMan for your RDP connections.

In this article, we'll explore what it is, how you can use it, and the differences between mRemoteNG and RDCMan. We'll also discuss alternatives to this tool.

So, let's dive in and learn how to use Microsoft's RDCMan to manage your remote connections like a pro!


What is RDCMan?

RDCMan (Remote Desktop Connection Manager) is a free Microsoft tool that helps you manage multiple desktop connections remotely. Think of it like having a remote control for all the computers you need to access. It allows users to organize and group their connections to simplify switching between them. 

Without remote connections, it would be challenging for SysAdmins and IT professionals to manage an organization's IT infrastructure effectively. The main reason behind this is that they would be forced to perform even the smallest task on-site, which isn't very practical considering the time and budget constraints.

However, with the help of RDCMan, IT professionals and system administrators can remotely:

  • Manage and maintain servers, workstations, and other devices.
  • Access and troubleshoot systems.
  • Manage and deploy software updates.
  • Monitor system performance and resource usage.
  • Provide technical support to users.

This would all be amazing if not for the fact that, in 2020, a developer exposed a security vulnerability in the software. As a result, Microsoft had to withdraw it. Let's find out what happened and how they resolved it.

RDCMan vulnerability

In March 2020, a security researcher discovered a vulnerability in the software that allowed attackers to execute code remotely on the target system. It resulted from a weakness in how RDCMan handled certain types of files. These files were .rdg extensions used to store connection settings in RDCMan. 

The exploit enabled an attacker to create a malicious .rdg file and easily trick the user into opening it with RDCMan. It would then execute the attacker's code on the target system, giving the attacker access to sensitive information or control of the system.

Microsoft quickly released a patch to fix the vulnerability in RDCMan version 2.7. They urged users to update to the latest version of the tool, which included a validation mechanism for opening the .rdg files.

It's essential to keep in mind that, as with any software, you must regularly update it to receive the latest security patches and fixes. And the same advice goes for your company software – something that InvGate Insight can do for you in just a few clicks.



How to use RDCMan?

RDCMan is an excellent tool if you frequently connect with remote computers. In addition, you can use it to manage and maintain remote servers, including monitoring performance, applying updates, and configuring settings. Also, it makes working from home or on the go easier since you can remotely connect to your workstations.

Without it, you would have to enter the password each time you connected with the target system. But with it, you can not only connect but also troubleshoot issues on other computers, organize connections into groups, and increase security by setting up custom settings.

Overall, the tool helps IT professionals seamlessly switch between different systems, saving time and improving their work efficiency.

How to install Remote Desktop Connection Manager?

Now that you know how to use the tool, let's look at the steps for installing it on your system.

  1. Download the latest version of RDCMan from the Microsoft website. The current version is v2.92 and is a part of Sysinternals. Make sure to download it from the above link, as it is the safe version.


  2. Unlike the previous version, the latest version of RDCMan doesn't require installation. So, once the download is complete, click the zip file named RDCMan.

  3. Now, extract the files from the folder.


  4. Once the extraction of the files is complete, you can start using the tool.
