This article provides workarounds for an issue where Remote Assistance connection to a Windows Server-based server that has FIPS encryption doesn't work.
Applies to: Windows Server 2016, Windows Server 2012 R2 Original KB number: 811770
Symptoms
Microsoft has added the FIPS Compliant setting to the options for Terminal Services encryption levels in Windows Server. A Windows Server-based server that has the encryption level set to FIPS Compliant cannot allow Remote Assistance connections from a computer that is running Windows 10.
When you try to connect from a Windows 10-based client to a Terminal Services server, the connection may not succeed, and you may receive the following error message:
Because of a security error, the client could not connect to the terminal server. After making sure that you are logged on to the network, try connecting to the server again.
Cause
This issue occurs because a Windows 10-based computer cannot provide a Remote Assistance connection to a Windows Server-based computer that is configured to require FIPS-compatible encryption.
Resolution
To resolve this problem, install Remote Desktop Connection 6.0. For more information about Remote Desktop Connection, click the following article number to view the article in the Microsoft Knowledge Base:
Remote Desktop Connection (Terminal Services Client 6.0) can be installed on client computers that are running Windows 10.
To work around this problem in Windows 10, disable the FIPS encryption level. To disable the FIPS encryption level, you can change the Encryption level setting in the RDP-Tcp Properties dialog box, or you can use the Group Policy Object to disable FIPS data encryption system-wide. To disable the FIPS encryption level, use one of the following methods.
Note
There are two ways to enable the FIPS encryption level. If you have to disable the FIPS encryption level for Terminal Services, you must do this by using the same method that you originally used to enable the FIPS encryption level.
Method 1
To disable the FIPS encryption level by changing the Encryption level setting in the RDP-Tcp Properties dialog box, follow these steps:
Click Start, click Run, type tscc.msc in the Open box, and then click OK.
Click Connections, and then double-click RDP-Tcp in the right pane.
In the Encryption level box, click to select a level of encryption other than FIPS Compliant.
Note
If the Encryption level setting is disabled when you try to change it, the system-wide setting for System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing has been enabled, and you must disable this system-wide setting by using method 2.
Method 2
To use the Group Policy Object to disable FIPS data encryption system-wide, follow these steps:
Click Start, click Run, type gpedit.msc in the Open box, and then click OK.
Expand Computer Configuration, expand Windows Settings, expand Security Settings, expand Local Policies, and then click Security Options.
In the right pane, double-click System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing, click Disable, and then click OK.
Note
Encryption level settings in Terminal Server are unavailable when FIPS is enabled.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
More information
The FIPS Compliant setting requires that all data between the client and the server is encrypted by using encryption methods that are validated by Federal Information Processing Standard 140-1. When a Windows 10-based client tries to connect to a Windows Server-based computer that requires FIPS-compliant encryption, the following errors occur:
On the client, you receive the following error message from Remote Assistance:
A Remote Assistance connection could not be established. You may want to check for network issues or determine if the invitation expired or was cancelled by the person who sent it.
The following error is logged in the System log on the server:
Event ID: 50 Source: TermDD Type: Error Description: The RDP protocol component "DATA ENCRYPTION" detected an error in the protocol stream and has disconnected the client.

PowerShell remoting is enabled by default on Windows Server platforms. You can use Enable-PSRemoting to enable PowerShell remoting on other supported versions of Windows and to re-enable remoting if it becomes disabled. You have to run this command only one time on each computer that will receive commands.
Save this answer. Show activity on this post. The local port is the port number on the local computer, in this case your Windows 2016 server. The remote port is the port number on the remote computer, in this case the client that is connecting to your SQL server.
Port 443 is a virtual port that computers use to divert network traffic. Billions of people across the globe use it every single day. Any web search you make, your computer connects with a server that hosts that information and fetches it for you. This connection is made via a port – either HTTPS or HTTP port.
Microsoft Remote Assistance (MSRA) is available in Windows 7, 8 and 10. It allows you to request assistance from a friend, who can then observe your system while you are working or control the system remotely.
A successful MSRA outcome will be valid for the entirety of the recruitment year in which it was undertaken (this is for GP specifically). If you get a good score and choose to re-apply in a subsequent round within the same recruitment year, your score will carry over.
Press the Windows key and the R key at the same time to open the Run command box, type in msra and hit Enter. This should open up Windows Remote Assistance in no time. Just click the Start button and directly type “remote assistance“. The search box will show up and deliver the results.
Click Start, point to Administrative Tools, and then click Active Directory Users and Computers. Right-click the user account that you want to allow remote access, and then click Properties. Click the Dial-in tab, click Allow access, and then click OK. Close the UserAccountProperties dialog box.
The MSRA is a computer-based exam which is designed to assess essential competencies. It is currently used for entry in postgraduate medical training for the following specialities: General Practice. Core Psychiatry Training. Clinical Radiology.
The MSRA is a computer-based assessment. It lets us assess whether you have the competences needed to for your chosen specialty and is based around clinical scenarios.
The full name of MRSA is methicillin-resistant Staphylococcus aureus. You might have heard it called a "superbug". MRSA infections mainly affect people who are staying in hospital. They can be serious, but can usually be treated with antibiotics that work against MRSA.
Don't underestimate the difficulty of the MSRA, start studying early, and do as many questions as you can afford to. It will pay off. All the question banks were good, and it is great to get used to as many formats as possible.
The date by which you can expect your results is disclosed in the recruitment timeline for each round. The results will be published in your Oriel account against your GP ST1 application as interview scores.
Methicillin-resistant Staphylococcus aureus (MRSA) can survive on some surfaces, like towels, razors, furniture, and athletic equipment for hours, days, or even weeks.
