Check RDP Service Status
First, ensure that the Remote Desktop Services are running. Open the Services console by pressing Windows + R, typing services.msc, and hitting Enter. Locate Remote Desktop Services in the list and check if its status is "Running." If it’s stopped, right-click on it, select "Start", and set the startup type to "Automatic" to avoid future interruptions.
For a more detailed check, open PowerShell with administrator privileges. Run the command Get-Service -Name "TermService" to verify the service status. If it’s not running, start it using Start-Service -Name "TermService". You can also check related services like Remote Desktop Configuration and Remote Desktop Services UserMode Port Redirector using the same commands.
Additionally, check the Terminal Services registry key. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server and confirm that the fDenyTSConnections value is set to 0. If it’s set to 1, RDP connections are disabled, and you’ll need to change it to 0.
Fix Firewall and Network Problems
Once you’ve verified the RDP service, address any potential network or firewall issues. Open Windows Defender Firewall with Advanced Security and check both inbound and outbound rules for Remote Desktop. Look for rules allowing traffic on TCP port 3389. If these rules are missing or disabled, create new ones or enable the existing ones.
To create a new inbound rule:
- Open the Actions panel and choose "New Rule."
- Select "Port" as the rule type, choose TCP, and specify port 3389.
- Allow the connection and apply the rule to all profiles (Domain, Private, and Public).
- Name the rule something clear, like "RDP Allow Inbound."
Also, review Network Level Authentication (NLA) settings in System Properties under the Remote tab. While NLA adds security, it can sometimes cause compatibility issues with certain client setups. Temporarily disable NLA to see if it resolves the error. If it does, re-enable it once the connection is stable.
After addressing network issues, ensure user permissions are configured correctly.
Review User Access and Security Settings
If the network setup is correct, the issue could be related to user access. Open Local Users and Groups by running lusrmgr.msc. Under Groups, double-click Remote Desktop Users and confirm that the necessary users are added to this group.
Next, check Local Security Policy settings for any restrictions. Run secpol.msc and navigate to Local Policies > User Rights Assignment. Look for Allow log on through Remote Desktop Services and ensure your user or group is listed. Also, check Deny log on through Remote Desktop Services to confirm your account isn’t explicitly blocked.
If issues persist, review Group Policy settings for Remote Desktop Services. Run gpedit.msc and go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections. Make sure policies like Allow users to connect remotely by using Remote Desktop Services are set to "Enabled" or "Not Configured."
Finally, inspect the registry key at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp. Check the SecurityLayer value. A value of 2 enforces SSL/TLS encryption, which may cause compatibility problems with older RDP clients. You can temporarily set it to 1 for RDP security or 0 for no security layer to test the connection.
Password policies can also block RDP access. If you’re using a local account, ensure the password meets Windows complexity requirements. Note that RDP doesn’t allow connections with empty passwords, even if local logons do.
