N-Central, Take Control RDP Connections not working

N‑able™ Take Control is a remote support solution which has troubleshooting tools designed to help you resolve issues quickly and effectively.

The Take Control tool on N-Able is the default and preferred (mostly) tool to connect to any server or workstation. But sometimes, there are problems quite frequently wherein the Take Control does not work for various reasons.

The alternative in such cases is using RDP to connect to the device. However, in such cases, we need RDP to be enabled on the device before we can use this option. In some cases, because we don’t have access to the server, it is not possible to enable RDP.

To work around this issue, we can add a registry key via the N-Able Tools command line. This is done to enable RDP remotely on the server without having to access the server. However, please note that the device needs to have N-central Professional License and “Direct Support” enabled under N-Able Device settings.


In the device view on N-central, Navigate to Tools > Command prompt

Paste the below mentioned key to ensure RDP connections are accepted:
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server” /vfDenyTSConnections /t REG_DWORD /d 0 /f


In some cases, after entering the login credentials the server returns the error: “An authentication error has occurred. The function requested is not supported. Remote computer: <computer name or IP>. This could be due to CredSSP encryption oracle remediation.


What is CredSSP?

CredSSP stands for Credential Security Support Provider protocol. As the name itself suggests, CredSSP is a Security Support Provider and it is implemented by using the SSPI – Security Support Provider Interface.


Why does a CredSSP error occur?

It occurs if you are trying to establish an unsecured RDP connection and if the connection is blocked by an Encryption Oracle Remediation policy setting on the server or client. This setting defines how to build an RDP session by using CredSSP, and whether an unsecured RDP is allowed.

This error usually is caused when CredSSP updates are not installed on the client or the server, or when the Windows updates on the server are not up to date. Ideally, to resolve the issue, CredSSP updates need to be installed for both client and server so that RDP can be established in a secure manner.

However, if this error still comes up, even after installing the updates, or for some reason, you are unable to install the updates and need to access the server, the error can be bypassed via another registry key. Again, the N-central license requirements need to be in place for the Tools to work.

If presented with a credSSP issue, paste the following key:
REG ADD “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters” /v AllowEncryptionOracle /t REG_DWORD /d 2

and the issue should be resolved.

n-central take control heart beat


  1. After a few seconds, go to the folder C:\Program Files (x86) and rename “BeAnywhere Support Express” as “BeAnywhere Support Express.old”. Please note that this can also be done remotely via NCentral File System Tool if the machine is assigned a Professional License


  1. Once that is done go back to Settings -> Properties and enable the check box to Install Take Control.

How to re-install N-Central agent without reconfiguration

Sometimes the N-central Agent gets corrupted, or the agent does not update after the N-central upgrade. This blog will teach you how you can re-install N-central agents on Servers and Workstations without having to reconfigure. The reasons why the agent stops communication could be because of technical issues or because it got accidentally uninstalled. You can choose to either reinstall it from the device on N-central-  works only if there is a probe set up for that site or if the IP address that N-central shows is the correct IP address for that device. Or you can go for the second option which is to re-install the agent using an activation key.

Solarwinds MSP renamed itself to N-able and N-central is their RMM tool.

Activation Key Method to reinstall N-central RMM agent

Open the device on N-central and go to Settings -> Local Agent
Download the Generic Agent installer from the path (circled in red below)


Run the downloaded installer and click on Next which will take you to the Agent Configuration. You will find the option for “Activation Key” on that page.

The Activation Key can be found on the same page from where the agent installer was downloaded. Click on the “Copy Activation Key” button and then copy the activation key from there.


Paste the copied activation key into the installer window (as shown below).


Once you do this, proceed with the further steps of the installer, as instructed.

The agent should be fixed on N-central as soon as the installation is done. It’ll be in the same configuration and setup as the original.
