Remote Connection: An authentication error has occured

When trying to connect to a Remote desktop I am receiving the following error. 

The above error has occured due to microsoft update. The following changes has to be done on your PC to connect to the Remote Desktop.

Fix No 1: 

Go to Run --> gpedit.msc --> Computer Configuration --> Administrative Template --> System --> Credentials Delegation --> Click on Encryption Oracle Remediation

Set "Encryption Oracle Remediation" to Enabled and "Protection Leven" to Vulnerable. Click on Apply and Ok.

Fix No 2:

For me when i went to RUN and enter gpedit.msc, I go an error saying windows couldn't find it. So went ahead with the following fix.

Go to RUN --> Enter REGEDIT click ok --> Computer -> HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Policies -> System

Right Click on System --> New --> Key --> rename the folder as "CredSSP"

Again Right Click on CredSSP --> New --> Key --> rename folder as "Parameters"

Again Right Click on Parameters --> New --> "DWORD (32-bit) Value" --> Enter filename as "AllowEncryptionOracle". Double click on AllowEncryptionOracle and set Value to "2".

Any of the above fixes and resolve the RDP issue.

Install or Enable Hyper-V on windows servers

Steps to install or enable Hyper-V is mostly same for any windows servers.

Go to "Programs and Features" --> Click on "Turn on windows features on or off" --> Select Hyper-V --> Install those features.

What if "Hyper-V Platform" is disabled in above windows features?

Then you have to enable Virtualization in the BIOS. This depends based on your Mother board. As I am using ASUS MB Gaming X570-PLUS mother board, I did following steps. Depending on your mother board you can google and enable virtualization.

Go to BIOS --> Advanced --> CPU Configuration --> Set SVM Mode to Enabled.

Now you can repeat the above steps again to install the Hyper-V features.
