Remote Desktop Protocol (RDP) is a powerful tool that allows users to access a computer remotely. However, users sometimes encounter errors such as “The remote resource can’t be reached.” This issue can be frustrating, especially when trying to establish a connection for work or personal tasks. In this guide, we will explore the possible causes and solutions to fix why the Remote Resource can’t be reached Remote Desktop.
Common Causes of the Error
Several factors can lead to the “The remote resource can’t be reached” error, including:
- Network Connectivity Issues – Unstable or disconnected networks can prevent RDP from functioning properly.
- Incorrect Remote Desktop Settings – Misconfigured settings on either the client or the host computer can block the connection.
- Firewall or Security Software Blocking RDP – Windows Firewall or third-party security software may prevent RDP connections.
- DNS or IP Address Issues – If the client cannot resolve the host computer’s address correctly, the connection may fail.
- Remote Desktop Services Not Running – The required services for RDP might be disabled or not functioning correctly.
- Incorrect Credentials – Using the wrong username or password can result in a failed connection attempt.
- ISP Restrictions – Some Internet Service Providers (ISPs) block port 3389 (the default RDP port) for security reasons.
- Remote Computer is Turned Off or in Sleep Mode – If the target computer is not active, RDP cannot establish a connection.
Step-by-Step Solutions Why The Remote Resource Can’t Be Reached Remote Desktop
1. Check Your Network Connection
Before troubleshooting deeper, ensure both the client and remote computers have active internet connections.
- Restart your device, for example: router or modem to refresh the network.
- Run ping <remote_IP> in the command prompt to test connectivity.
- Try accessing other websites to confirm the internet is working properly.
2. Verify Remote Desktop is Enabled on the Host Computer
To check if RDP is enabled:
- Press Win + I to open Settings.
- Navigate to System > Remote Desktop.
- Ensure the toggle for Enable Remote Desktop is switched to “On”.
- Click on Advanced settings and make sure Require Network Level Authentication is enabled.
3. Allow RDP Through Windows Firewall
Windows Defender Firewall may block Remote Desktop connections. To allow it:
- Open the Control Panel and go to Windows Defender Firewall.
- Press Permit an app or feature through Windows Defender Firewall.
- Find a Remote Desktop and ensure both Private and Public networks are checked.
- Click OK and restart your computer.
If you use third-party security software, ensure it is not blocking RDP.
4. Confirm the Remote Desktop Services Are Running
The RDP services must be enabled for a successful connection.
- Press Win + R, & write services.msc, & hit Enter.
- Locate the following services:
- Remote Desktop Services
- Remote Desktop Configuration
- Remote Desktop Services UserMode Port Redirector
- Right-click each service and select Restart.
- Ensure their startup type set to Automatic.
5. Check the Remote Computer’s IP Address and Hostname
If using a hostname, ensure it resolves to the correct IP address:
- Open Command Prompt on the client machine.
- Type nslookup <hostname> and press Enter.
- Compare the returned IP with the remote machine’s actual IP.
Alternatively, check the remote computer’s IP:
- Press Win + R, type cmd, & press Submit.
- Run ipconfig and note the IPv4 Address.
- Use this IP address when connecting via RDP.
6. Modify the Hosts File for DNS Resolution Issues
If DNS resolution fails, manually add an entry in the hosts file:
- Open Notepad as Administrator.
- Open the file: C:\Windows\System32\drivers\etc\hosts.
- Add an entry in this format:
<remote_computer_IP> <remote_computer_hostname>
- Save the file and restart the connection.
7. Change RDP Port If Blocked by ISP
Some ISPs block port 3389, preventing Remote Desktop from working.
To change the RDP port:
- Open Registry Editor (regedit).
- Navigate to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp.
- Find PortNumber, double-click it, choose Decimal, and enter a new port (e.g., 4589).
- Update port forwarding rules on your router if necessary.
- Restart your computer and reconnect using the new port (<IP>:<new_port>).
8. Ensure the Remote Computer is Awake
If the remote PC is in sleep mode, RDP won’t work.
- Go to Settings > System > Power & Sleep and set it to Never (for testing purposes).
- Use Wake-on-LAN (WoL) if necessary to wake up the remote PC before connecting.
9. Reset Remote Desktop Connection Credentials
Incorrect credentials can cause this error.
- Open Remote Desktop Connection (mstsc).
- Click Show Options.
- Navigate to the General tab.
- Click Delete credentials.
- Re-enter the username and password.
- Try connecting again.
10. Use a VPN for Secure Remote Access
If RDP blocked due to security policies, a VPN (Virtual Private Network) can help by securely tunneling traffic.
Popular VPN solutions include:
Setting up a VPN allows your device to connect to the remote network as if it were local, bypassing restrictions.
Final Thoughts
Encountering the “The remote resource can’t reached” error in Remote Desktop can be frustrating, but by following these troubleshooting steps, you can diagnose and resolve the issue effectively. Whether it’s a network misconfiguration, firewall blocking, or a service-related problem, addressing each possible cause systematically will increase the chances of a successful connection.
If the problem persists despite all these fixes, consider using alternative remote access tools such as Chrome Remote Desktop, AnyDesk, or TeamViewer for a hassle-free remote connection experience.
