How to Fix RDP Only Allowing 1 Connection? Enable Multiple Sessions

/ Knowledgebase, Remote Desktop Protocol (RDP)

-One common limitation encountered by users is that RDP only allows a single session at a time. This can be frustrating for administrators and users who need multiple concurrent remote desktop connections. In this blog post, we will explore why RDP only allowing 1 connection, how to enable multiple connections, and alternative solutions.

Why RDP Only Allowing 1 Connection

By default, Windows operating systems limit RDP connections to a single session for the following reasons:

  1. License Restrictions: Windows 10, Windows 11, and some editions of Windows Server enforce a single-user session due to licensing constraints.
  2. Security Considerations: Restricting RDP to one session reduces the risk of unauthorized access and enhances system security.
  3. Performance Optimization: Allowing only one session helps preserve system resources, especially on machines with limited CPU and RAM.

How to Enable Multiple RDP Merger on Windows Server

If you are using a Windows Server edition (such as Windows Server 2019 or Windows Server 2022), you can enable multiple RDP sessions by following these steps:

Step-1: Modify Group Policy Settings

  1. Open the Run dialog by pressing Win + R and type gpedit.msc, then hit Enter.
  2. Navigate to Personal Desktop Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Connections.
  3. Locate & double-click “Restrict Remote Desktop Services users to a single RDP session”.
  4. Select Disabled, then click Apply and OK.

Step-2: Increase Maximum Connections

  1. In the same Group Policy Editor, locate “Limit number of connections”.
  2. Double-click it and select Enabled.
  3. Set the Maximum Connections to a higher number (e.g., 2 or more).
  4. Click Apply and OK.

Step-3: Restart Remote Desktop Services

  1. Open Command Prompt as an administrator.
  2. Type the following commands:
    net stop termservice
net start termservice
  3. Restart the computer to apply changes.

How to Enable Multiple RDP Connections on Windows 10/11

For non-server editions, enabling multiple RDP sessions requires third-party tools or registry modifications.

Step 1: Modify the Windows Registry

  1. Open the Run dialog (Win + R) button, type regedit, & press Enter.
  2. Navigate to the following key:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server
  3. Find the fSingleSessionPerUser value and double-click it.
  4. Change the Value Data from 1 to 0.
  5. Click OK and restart your computer.

Step 2: Use RDP Wrapper

Since Windows 10/11 Home and Pro editions do not support multiple RDP sessions natively, an open-source tool called RDP Wrapper can enable this functionality. However, use this tool at your own risk.

  1. Download RDP Wrapper from a trusted source.
  2. Install it and run the configuration utility.
  3. Restart your computer and test multiple RDP connections.

Alternative Solutions

If enabling multiple RDP sessions is not an option, consider the following alternatives:

  1. Use Windows Server with RDS Licensing: Windows Server with Remote Desktop Services (RDS) licenses allows multiple concurrent connections.
  2. Third-Party Remote Desktop Software: Applications like AnyDesk, TeamViewer, and Chrome Remote Desktop support multiple connections.
  3. Virtual Machines (VMs): Running virtual machines can allow multiple users to connect separately.

Conclusion

By default, Windows restricts RDP to one session per user, but with the right configuration changes, you can enable multiple connections on Windows Server and even non-server editions with workarounds. Always ensure that your RDP settings align with licensing policies and security best practices.
