Can't RDP Into Server? Solve Remote Desktop Connection Issues

Is “Can’t RDP into server” your current headache? At rental-server.net, we understand the frustration of Remote Desktop Protocol (RDP) connection problems and offer streamlined server solutions to resolve them. We will guide you through a series of checks and fixes to get your remote access up and running again.

1. What is RDP and Why Can’t I Connect to My Server?

RDP, or Remote Desktop Protocol, is a Microsoft-developed protocol that allows you to connect to and control a remote computer over a network connection. If you can’t RDP into server, several factors could be at play, ranging from simple configuration errors to more complex network issues. According to a study by the Uptime Institute, network misconfigurations are a leading cause of remote access failures.

1.1. Understanding Common RDP Connection Issues

RDP connection issues can stem from various sources, including:

Incorrect RDP settings: RDP might be disabled on the remote computer or configured incorrectly.
Firewall restrictions: Firewalls can block the RDP port (typically 3389), preventing connections.
Network problems: Network connectivity issues can prevent the client from reaching the remote server.
Service status: The Remote Desktop Services might not be running on the remote server.
Group Policy conflicts: Group policies can override RDP settings and block connections.
Listener Issues: The RDP listener might not be functioning correctly.

1.2. Key Areas to Investigate When You Can’t RDP Into Server

When troubleshooting RDP connection problems, focus on these key areas:

RDP Status: Is RDP enabled on the remote server?
Firewall Configuration: Is the RDP port open in the firewall?
Network Connectivity: Can the client reach the remote server over the network?
Service Status: Are the Remote Desktop Services running?
Group Policy: Are any group policies blocking RDP connections?
Listener: Is the RDP Listener functioning properly and listening on the correct port?
Authentication: Are there any authentication or certificate issues?

2. How to Check the Status of the RDP Protocol?

The first step in troubleshooting RDP connection issues is to verify that RDP is enabled on the remote computer.

2.1. How to Check the RDP Protocol on a Local Computer?

To check the status of the RDP protocol on a local computer, follow these steps:

Open Settings on your computer.
Click on System, then select Remote Desktop.
Make sure the Remote Desktop slider is set to On.

2.2. How to Check the RDP Protocol on a Remote Computer?

If you can’t access the remote computer directly, you can check the RDP status using the Registry Editor over the network.

Warning: Incorrectly modifying the registry can cause serious problems. Back up the registry before making any changes.

Open the Run dialog box by pressing Win + R, then type regedt32 and press Enter.
In the Registry Editor, select File, then select Connect Network Registry.
Enter the name of the remote computer, select Check Names, and then select OK.
Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal Server and to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows NTTerminal Services.

If the value of the fDenyTSConnections key is 0, RDP is enabled.
If the value of the fDenyTSConnections key is 1, RDP is disabled.

To enable RDP, change the value of fDenyTSConnections from 1 to 0.

2.3. What to do if Remote Desktop Options are Not Available?

If the remote desktop options are not available or the value of fDenyTSConnections reverts to 1 after you change it, a Group Policy Object (GPO) may be overriding the computer-level settings.

3. How to Check Whether a Group Policy Object (GPO) is Blocking RDP?

Group Policy Objects (GPOs) can override local settings and prevent RDP connections. It’s essential to check the GPO configuration to ensure that no policies are blocking RDP.

3.1. Checking GPO on a Local Computer

To check the group policy configuration on a local computer, follow these steps:

Open a command prompt window as an administrator.
Enter the following command:

gpresult /H c:gpresult.html

After this command finishes, open gpresult.html in a web browser.
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.

3.2. Checking GPO 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:

gpresult /S <computer name=""> /H c:gpresult-<computer name="">.html

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

3.3. How to Modify a Blocking GPO?

You can modify these settings in the Group Policy Object Editor (GPE) and Group Policy Management Console (GPM). To modify the blocking policy, use one of the following methods:

Using GPE:
1. Access the appropriate level of GPO (such as local or domain).
2. 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.
3. Set the policy to either Enabled or Not configured.
4. On the affected computers, open a command prompt window as an administrator and run the gpupdate /force command.
Using GPM:
1. Navigate to the organizational unit (OU) in which the blocking policy is applied to the affected computers.
2. Delete the policy from the OU.

4. Are the RDP Services Running? Checking the Status of RDP Services

For RDP to function correctly, the following services should be running on both the local (client) computer and the remote (target) computer:

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

4.1. How to Manage Services Using the Services MMC Snap-In

You can use the Services MMC snap-in to manage the services locally or remotely.

Press Win + R, type services.msc, and press Enter.
Locate the Remote Desktop Services and Remote Desktop Services UserMode Port Redirector services.
Check the Status column to see if the services are running.
If one or both services are not running, right-click the service and select Start.

4.2. How to Manage Services Using PowerShell

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

Open PowerShell as an administrator.
To check the status of a service, use the following command:

Get-Service -Name "TermService" | Select-Object -Property Name, Status

To start a service, use the following command:

Start-Service -Name "TermService"

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

5. How to Check That the RDP Listener is Functioning?

The RDP listener must be functioning correctly for RDP connections to be established.

5.1. Checking the Status of the RDP Listener Using PowerShell

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.

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

Enter-PSSession -ComputerName <computer name="">

Enter qwinsta.
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.
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

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.
Copy the exported .reg file to the affected computer.
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:

cmd /c 'reg export "HKLMSYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-tcp" C:Rdp-tcp-backup.reg'

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

Remove-Item -path 'HKLM:SYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-tcp' -Recurse -Force

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

cmd /c 'regedit /s c:<filename>.reg'
Restart-Service TermService -Force

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

Test the configuration by trying the remote desktop connection again. If you still can’t connect, restart the affected computer.
If you still can’t connect, check the status of the RDP self-signed certificate.

5.2. How to Check the Status of the RDP Self-Signed Certificate?

If you still can’t connect, follow these steps to check the status of the RDP self-signed certificate:

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.
In the Certificates folder under Remote Desktop, delete the RDP self-signed certificate.
On the affected computer, restart the Remote Desktop Services service.
Refresh the Certificates snap-in.
If the RDP self-signed certificate has not been recreated, check the permissions of the MachineKeys folder.

5.3. How to Check the Permissions of the MachineKeys Folder?

If the RDP self-signed certificate has not been recreated, check the permissions of the MachineKeys folder.

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

6. What Port Should the RDP Listener Use? Check the RDP Listener Port

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

6.1. How to Check or Change the RDP Port Using the Registry Editor?

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

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.
Open the registry and navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTerminal ServerWinStations.
If PortNumber has a value other than 3389, change it to 3389.

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

6.2. How to 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.

Open a PowerShell window. To connect to a remote computer, enter Enter-PSSession -ComputerName <computer name="">.
Enter the following command:

cmd /c 'netstat -ano | find "3389"'

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

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

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

cmd /c 'tasklist /svc | find "<pid listening="" on="">"'

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.
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).

7. Is the Firewall Blocking RDP?

A firewall can block the RDP port, preventing connections.

7.1. How to Check Whether a Firewall is Blocking the RDP Port Using `psping`

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

Go to a different computer that isn’t affected and download psping.
Open a command prompt window as an administrator, change to the directory in which you installed psping, and then enter the following command:

psping -accepteula <computer ip="">:3389

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.
Run psping on multiple computers to test their ability to connect to the affected computer.
Note whether the affected computer blocks connections from all other computers, some other computers, or only one other computer.

7.2. Recommended Next Steps When a Firewall is Blocking RDP

Engage your network administrators to verify that the network allows RDP traffic to the affected computer.
Investigate the configurations of any firewalls between the source computers and the affected computer (including Windows Firewall on the affected computer) to determine whether a firewall is blocking the RDP port.
