Problem description:

The following error occurs when the remote desktop connects to the server

An authentication error occurred. The required function is not supported

However, some clients do not have this problem when they connect to the server, that is, there is a problem with this client connection.

Solution:

First, modify it in the remote desktop client

Start running-> gpedit.msc Open Local Security Policy

Policy path: computer configuration-> Administrative templates-> system-> credential assignment

Set the name "encrypted Oracle fix" to enabled and vulnerable, and make sure it is OK.

The item "encryption Oracle correction" can not be found on the personal computer, nor does it have the KB4103718 patch recently updated by Microsoft. In this case, modify the registry an and open the registry and type "regedit" quickly.

(similar to finding a command prompt and typing cmd)

B find the folder path: [HKEY_LOCAL_MACHINE]\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ System\ CredSSP\ Parameters

Generally, there will be no more after System. You can create your own folder.

C and then create a new DWORD (32) bit in the bottom folder.

Key value "AllowEncryptionOracle", value: 2

D Last click Save to log in to the remote Desktop (restart it if necessary)

Another simple method: (same effect as above)

You can also copy the following directly to notepad:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ System\ CredSSP\ Parameters]

"AllowEncryptionOracle" = dword:00000002

Name it at will, change the txt suffix to reg, open it and run it, and then import it into the registry automatically.

+

Turn off authentication on the remote server

Through the above method settings, the remote desktop client can connect to the server, click Yes or No to connect, and no longer report authentication errors
