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.

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

The full error reads “The authentication certificate received from the remote computer has expired or is not valid”. You may receive this error when you start Remote Desktop Connection and the cause is the date and time settings on your computer. You may encounter this when the two computers don’t have the same date.
To fix the problem, set the correct date or just synchronize it with an internet time server. To do this, right-click date and time on the system tray and select “Adjust date/time”. In “Date and Time” dialog, under “Date and Time” tab, click “Change time zone” then select your correct time zone on the next screen and then click “OK”.
Next, go to “Internet Time” tab then click “Change settings”. In “Internet Time Settings” dialog, make sure “Synchronize with an Internet time server” is checked. In “Server”, select a time server from the dropdown list then click “Update now”. In Windows 7, you can select between:
- time.windows.com
- time.nist.gov
- time-nw.nist.gov
- time-a.nist.gov
- time-b.nist.gov
In Windows XP, there are only two options available:
- time.nist.gov
- time.windows.com
Click “OK” all throughout then try Remote Desktop Connection again and see if it works. If this doesn’t work, repeat the same steps on the other computer. It should fix the problem.
