Windows RDP: Solving the error "This could be due to CredSSP encryption oracle remediation"

Do you get the error as below when remoting your server?

It is normally caused by your Windows client getting new update on CredSSP but your Windows server is not.
For long term, you should update your server for more security.
For temporary solution, you can do the following steps on your Windows client to able to remote your server:

1. Open Run box, key gpedit.msc to open Local Group Policy Editor.

2. Navigate to Computer Configuration >> Administrative Templates >> System >> Credentials Delegation >> Encryption Oracle Remediation. Then select  Enable >> Vulnerable >> OK.

3. Finally, open CMD (run as Administrator), run the command: gpupdate /force
to update the policy immediately.

Hope you can remote your server and update it. Have a nice day.
