After Remote Desktop client loses its connection to the remote desktop, the client can't immediately reconnect. The user receives one of the following error messages:

Dec 21, 2012  According to Microsoft, RDC will have problems in OSX Lion and greater. Copied info: 'Microsoft Remote Desktop Connection Client for Mac (version 2.1.1) is not intended for use with Mac OS X v10.7 (Lion) or later.' Here is a thread where someone got it working. Mar 20, 2019 On your Windows, Android, or iOS device: Open the Remote Desktop app (available for free from Microsoft Store, Google Play, and the Mac App Store), and add the name of the PC that you want to connect to (from Step 1). Select the remote PC name that you added, and then wait for the connection to complete.

• The client couldn't connect to the terminal server because of a security error. Make sure you are signed in to the network, then try connecting again.
• Remote Desktop disconnected. Because of a security error, the client could not connect to the remote computer. Verify that you are logged onto the network and then try connecting again.

When the Remote Desktop client reconnects, the RDSH server reconnects the client to a new session instead of the original session. However, when you check the RDSH server, it says that the original session is still active and didn't enter a disconnected state.

To work around this issue, you can enable the Configure keep-alive connection interval policy in the Computer ConfigurationAdministrative TemplatesWindows ComponentsRemote Desktop ServicesRemote Desktop Session HostConnections group policy folder. If you enable this policy, you must enter a keep-alive interval. The keep-alive interval determines how often, in minutes, the server checks the session state.

This issue can also be fixed by reconfiguring your authentication and configuration settings. You can reconfigure these settings at either the server level or by using group policy objects (GPOs). Here's how to reconfigure your settings: Computer ConfigurationAdministrative TemplatesWindows ComponentsRemote Desktop ServicesRemote Desktop Session HostSecurity group policy folder.

1. On the RD Session Host server, open Remote Desktop Session Host Configuration.
2. Under Connections, right-click the name of the connection, then select Properties.
3. In the Properties dialog box for the connection, on the General tab, in Security layer, select a security method.
4. Go to Encryption level and select the level you want. You can select Low, Client Compatible, High, or FIPS Compliant.

Note

• When communications between clients and RD Session Host servers require the highest level of encryption, use FIPS-compliant encryption.
• Any encryption level settings you configure in Group Policy override the settings you configured using the Remote Desktop Services Configuration tool. Also, if you enable the System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing policy, this setting overrides the Set client connection encryption level policy. The system cryptography policy is in the Computer ConfigurationWindows SettingsSecurity SettingsLocal PoliciesSecurity Options folder.
• When you change the encryption level, the new encryption level takes effect the next time a user signs in. If you require multiple levels of encryption on one server, install multiple network adapters and configure each adapter separately.
• To verify your certificate has a corresponding private key, go to Remote Desktop Services Configuration, right-click the connection that you want to view the certificate for, select General, then select Edit. After that, select View certificate. When you go to the General tab, you should see the statement, 'You have a private key that corresponds to this certificate' if there's a key. You can also view this information with the Certificates snap-in.
• FIPS-compliant encryption (the System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing policy or the FIPS Compliant setting in Remote Desktop Server Configuration) encrypts and decrypts data sent between the server and client with the Federal Information Processing Standard (FIPS) 140-1 encryption algorithms that use Microsoft cryptographic modules. For more information, see FIPS 140 Validation.
• The High setting encrypts data sent between the server and client by using strong 128-bit encryption.
• The Client Compatible setting encrypts data sent between the client and the server at the maximum key strength supported by the client.
• The Low setting encrypts data sent from the client to the server using 56-bit encryption.

Use these steps when a Remote Desktop client can't connect to a remote desktop but doesn't provide messages or other symptoms that would help identify the cause.

Check the status of the RDP protocol

Check the status of the RDP protocol on a local computer

To check and change the status of the RDP protocol on a local computer, see How to enable Remote Desktop.

Note

If the remote desktop options are not available, see Check whether a Group Policy Object is blocking RDP.

Check the status of the RDP protocol on a remote computer

Important

Follow this section's instructions carefully. Serious problems can occur if the registry is modified incorrectly. Before you starty modifying the registry, back up the registry so you can restore it in case something goes wrong.

To check and change the status of the RDP protocol on a remote computer, use a network registry connection:

1. First, go to the Start menu, then select Run. In the text box that appears, enter regedt32.
2. In the Registry Editor, select File, then select Connect Network Registry.
3. In the Select Computer dialog box, enter the name of the remote computer, select Check Names, and then select OK.
4. Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal Server.
   
   • If the value of the fDenyTSConnections key is 0, then RDP is enabled.
   • If the value of the fDenyTSConnections key is 1, then RDP is disabled.
5. To enable RDP, change the value of fDenyTSConnections from 1 to 0.

Check whether a Group Policy Object (GPO) is blocking RDP on a local computer

If you can't turn on RDP in the user interface or the value of fDenyTSConnections reverts to 1 after you've changed it, a GPO may be overriding the computer-level settings.

To check the group policy configuration on a local computer, open a Command Prompt window as an administrator, and enter the following command:

After this command finishes, open gpresult.html. In Computer ConfigurationAdministrative TemplatesWindows ComponentsRemote Desktop ServicesRemote Desktop Session HostConnections, find the Allow users to connect remotely by using Remote Desktop Services policy.

• If the setting for this policy is Enabled, Group Policy is not blocking RDP connections.

• If the setting for this policy is Disabled, check Winning GPO. This is the GPO that is blocking RDP connections.

Check whether a GPO is blocking RDP on a remote computer

To check the Group Policy configuration on a remote computer, the command is almost the same as for a local computer:

The file that this command produces (gpresult-<computer name>.html) uses the same information format as the local computer version (gpresult.html) uses.

Modifying a blocking GPO

You can modify these settings in the Group Policy Object Editor (GPE) and Group Policy Management Console (GPM). For more information about how to use Group Policy, see Advanced Group Policy Management.

To modify the blocking policy, use one of the following methods:

• In GPE, access the appropriate level of GPO (such as local or domain), and navigate to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections > Allow users to connect remotely by using Remote Desktop Services.
  1. Set the policy to either Enabled or Not configured.
  2. On the affected computers, open a command prompt window as an administrator, and run the gpupdate /force command.
• In GPM, navigate to the organizational unit (OU) in which the blocking policy is applied to the affected computers and delete the policy from the OU.

Check the status of the RDP services

On both the local (client) computer and the remote (target) computer, the following services should be running:

• Remote Desktop Services (TermService)
• Remote Desktop Services UserMode Port Redirector (UmRdpService)

You can use the Services MMC snap-in to manage the services locally or remotely. You can also use PowerShell to manage the services locally or remotely (if the remote computer is configured to accept remote PowerShell cmdlets).

On either computer, if one or both services are not running, start them.

Note

If you start the Remote Desktop Services service, click Yes to automatically restart the Remote Desktop Services UserMode Port Redirector service.

Check that the RDP listener is functioning

Important

Follow this section's instructions carefully. Serious problems can occur if the registry is modified incorrectly. Before you starty modifying the registry, back up the registry so you can restore it in case something goes wrong.

Check the status of the RDP listener

For this procedure, use a PowerShell instance that has administrative permissions. For a local computer, you can also use a command prompt that has administrative permissions. However, this procedure uses PowerShell because the same cmdlets work both locally and remotely.

1. To connect to a remote computer, run the following cmdlet:

2. Enter qwinsta.

3. If the list includes rdp-tcp with a status of Listen, the RDP listener is working. Proceed to Check the RDP listener port. Otherwise, continue at step 4.

4. Export the RDP listener configuration from a working computer.

   1. Sign in to a computer that has the same operating system version as the affected computer has, and access that computer's registry (for example, by using Registry Editor).
   2. Navigate to the following registry entry:
      HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-Tcp
   3. Export the entry to a .reg file. For example, in Registry Editor, right-click the entry, select Export, and then enter a filename for the exported settings.
   4. Copy the exported .reg file to the affected computer.

5. To import the RDP listener configuration, open a PowerShell window that has administrative permissions on the affected computer (or open the PowerShell window and connect to the affected computer remotely).

   1. To back up the existing registry entry, enter the following cmdlet:

   2. To remove the existing registry entry, enter the following cmdlets:

   3. To import the new registry entry and then restart the service, enter the following cmdlets:

      Replace <filename> with the name of the exported .reg file.

6. Test the configuration by trying the remote desktop connection again. If you still can't connect, restart the affected computer.

7. If you still can't connect, check the status of the RDP self-signed certificate.

Check the status of the RDP self-signed certificate

1. If you still can't connect, open the Certificates MMC snap-in. When you are prompted to select the certificate store to manage, select Computer account, and then select the affected computer.
2. In the Certificates folder under Remote Desktop, delete the RDP self-signed certificate.
3. On the affected computer, restart the Remote Desktop Services service.
4. Refresh the Certificates snap-in.
5. If the RDP self-signed certificate has not been recreated, check the permissions of the MachineKeys folder.

Check the permissions of the MachineKeys folder

1. On the affected computer, open Explorer, and then navigate to C:ProgramDataMicrosoftCryptoRSA.
2. Right-click MachineKeys, select Properties, select Security, and then select Advanced.
3. Make sure that the following permissions are configured:
   • BuiltinAdministrators: Full control
   • Everyone: Read, Write

Check the RDP listener port

On both the local (client) computer and the remote (target) computer, the RDP listener should be listening on port 3389. No other applications should be using this port.

Important

Follow this section's instructions carefully. Serious problems can occur if the registry is modified incorrectly. Before you starty modifying the registry, back up the registry so you can restore it in case something goes wrong.

To check or change the RDP port, use the Registry Editor:

1. Go to the Start menu, select Run, then enter regedt32 into the text box that appears.
   • To connect to a remote computer, select File, and then select Connect Network Registry.
   • In the Select Computer dialog box, enter the name of the remote computer, select Check Names, and then select OK.
2. Open the registry and navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinStations<listener>.
3. If PortNumber has a value other than 3389, change it to 3389.

   Important

   You can operate Remote Desktop services using another port. However, we don't recommend you do this. This article doesn't cover how to troubleshoot that type of configuration.

4. After you change the port number, restart the Remote Desktop Services service.

Check that another application isn't trying to use the same port

For this procedure, use a PowerShell instance that has administrative permissions. For a local computer, you can also use a command prompt that has administrative permissions. However, this procedure uses PowerShell because the same cmdlets work locally and remotely.

Microsoft Remote Desktop For Mac Download

1. Open a PowerShell window. To connect to a remote computer, enter Enter-PSSession -ComputerName <computer name>.

2. Enter the following command:

3. Look for an entry for TCP port 3389 (or the assigned RDP port) with a status of Listening.

   Note

   The process identifier (PID) for the process or service using that port appears under the PID column.

4. To determine which application is using port 3389 (or the assigned RDP port), enter the following command:

5. Look for an entry for the PID number that is associated with the port (from the netstat output). The services or processes that are associated with that PID appear on the right column.

6. If an application or service other than Remote Desktop Services (TermServ.exe) is using the port, you can resolve the conflict by using one of the following methods:

   • Configure the other application or service to use a different port (recommended).
   • Uninstall the other application or service.
   • Configure RDP to use a different port, and then restart the Remote Desktop Services service (not recommended).

Check whether a firewall is blocking the RDP port

Microsoft Remote Desktop Mac Keeps Disconnecting

Use the psping tool to test whether you can reach the affected computer by using port 3389.

1. Go to a different computer that isn't affected and download psping from https://live.sysinternals.com/psping.exe.

2. Open a command prompt window as an administrator, change to the directory in which you installed psping, and then enter the following command:

3. Check the output of the psping command for results such as the following:

   • Connecting to <computer IP>: The remote computer is reachable.
   • (0% loss): All attempts to connect succeeded.
   • The remote computer refused the network connection: The remote computer is not reachable.
   • (100% loss): All attempts to connect failed.

4. Run psping on multiple computers to test their ability to connect to the affected computer.

5. Note whether the affected computer blocks connections from all other computers, some other computers, or only one other computer.
