- When connecting to a remote desktop connection, you will need to verify your credentials before you can log in.
- This prevents unauthorized users from accessing your information and using your data.
- However, sometimes, your credentials cannot be verified so read on to find out how you can resolve it.
If you are trying to connect from a remote desktop and are getting an error that the connection has been denied, then this is most likely because you have not authenticated yet.
When you start a Remote Desktop Connection, it will prompt you to enter the credentials of the computer you are connecting to. You cannot proceed before your authentication details have been verified.
The reason it requires authentication is that RDP is intended to be used by an administrator. An administrator can connect to any computer on the network and manage it remotely. If it were left unsecured, anyone could connect to your computer and use it.
This would put the user’s data at risk as anyone with access could take advantage of their details for unscrupulous activities. Sometimes, you may encounter an RDP authentication error because of your settings.
Why won’t my remote desktop connection connect?
There are a few reasons why your remote desktop connection won’t connect. Here are the most common ones:
- Not enough permissions – The most common reason is that the computer you are trying to connect from does not have the correct permissions to access the target computer. This can happen if you are using a domain account with too low of a permission level, or if your account has been locked out for some reason.
- Your firewall is blocking the connection – Make sure that any firewalls you have installed on your computer, such as Windows Firewall or any other third-party firewall software, aren’t blocking access to Remote Desktop.
- The remote computer is offline or not responding – This can happen if a user turns off the remote computer or disconnects it from the network. Also, an intermittent network connection can cause such problems.
- Unsupported version – If you’re using an unsupported version of Windows Remote Desktop, you will need to upgrade to the latest version that is supported by your current OS.
- Poor network connection – You don’t need a strong internet connection for Remote Desktop. However, you do need a connection between your device and the remote computer. If you’re using a wired connection, make sure it’s plugged in and working properly.
If you suspect any of the above could be the cause of the error, proceed to our advanced troubleshooting steps.
