Remote Desktop Connection authentication certificate has expired or is not valid.

I have a Dell notebook located inside my room and a desk in our classroom. I am using Remote Desktop connection access from my desktop to my laptop. It worked well for a while, but when I returned me home after a long vacation, suddenly, remote access no longer works.

No one uses my computer, and I do not touch anything. I can see my desktop file sharing, which means my network works. I can not connect me, via connection to a remote desktop.

This is the error I get.

Remote Desktop Disconnected

The authentication certificate received from the remote computer has expired or is not valid.

OK Help

Any solutions would be greatly appreciated.

Thank you so much.

Hi!

There are reasons why you're getting that kind of error. It could be because the date on your computer is too far apart and is misreading the situation. You can try the following:

  1. Make sure the date between the two PC's are close or the same. Make sure they are both registering the right date to make sure that they can remote access with each other.  Perhaps, it is mistaken that the authentication has expired due to your PC's date gap is different.
  2. Synchronize the date of both your computers to the Internet to ensure that the date is set right.

Hope that helps.

Hi Rebecca,

Base on my research, usually, the caused of your problem is the time error between server and client. You have to keep your time often. Another cause is during your set up the server time was not set correctly. It should help if you will set the time correctly before restarting the server.

If this not work, please try the following step:

1. Start mmc.exe and open certificates snap-in for local computer account.

2. You have to navigate to "CertificatesRemote DesktopCertificates"

3. And you have to delete the certificates that's in this store

4. Finally, Restart the machine.

Hope it helps you.
