How to Remote Desktop To Another Computer Over the Internet


How to Remote Desktop to Another Computer Over the Internet In an increasingly digital world, the ability to remotely access another computer over the internet has become a critical tool for businesses, IT professionals, and even everyday users. Whether you're providing tech support, accessing files from your home PC while traveling, or managing servers, remote desktop access can save time and enhance productivity. This guide walks you through everything you need to know to set up and use Remote Desktop over the internet safely and efficiently.

What Is Remote Desktop?

Remote Desktop is a technology that allows you to connect and control another computer over a network or the internet as if you were sitting right in front of it. You can open files, run programs, and even troubleshoot issues remotely.

There are various tools and methods available to perform remote access, including:

  • Microsoft Remote Desktop (RDP)

  • TeamViewer

  • AnyDesk

  • Chrome Remote Desktop

  • Third-party VPN and Remote Access Tools

Each tool has its strengths, but the underlying concept remains the same: connecting to a remote machine securely and interactively.

Requirements for Remote Desktop Access

Before diving into the setup, make sure you meet the following basic requirements:

  1. Stable Internet Connection – Both the local (client) and remote (host) computers must be connected to the internet.

  2. Remote Access Enabled – The target (host) computer must have remote access enabled.

  3. Correct Credentials – You'll need the username and password for the remote system.

  4. Firewall and Router Configuration – Port forwarding may be required for connections across the internet.

  5. Security Measures – Use encryption, strong passwords, and trusted software to protect your data.

Method 1: Using Microsoft Remote Desktop (RDP)

Step 1: Enable Remote Desktop on the Host Computer

  1. On the host Windows PC, go to:

    • Settings > System > Remote Desktop

    • Toggle "Enable Remote Desktop" to ON.

  2. Note the computer name (you’ll need this to connect).

  3. Allow the PC through the firewall if prompted.

⚠️ Remote Desktop is only available on Windows Pro, Enterprise, or Education editions—not Windows Home.

Step 2: Set Up Port Forwarding on the Router

  1. Log in to the host computer’s router.

  2. Find the Port Forwarding section.

  3. Forward TCP port 3389 to the local IP address of the host computer.

  4. Save changes and reboot the router if needed.

🔐 Tip: Consider using a VPN instead of port forwarding for better security.

Step 3: Find the Host Computer’s Public IP Address

Visit https://whatismyipaddress.com from the host PC to get its public IP.

Step 4: Connect From the Client Computer

  1. Open Remote Desktop Connection (search "mstsc" in Windows).

  2. Enter the public IP address of the host computer.

  3. Enter the correct login credentials.

  4. Click "Connect."

You should now see the desktop of the remote computer and be able to control it.

Method 2: Using Chrome Remote Desktop

Google’s Chrome Remote Desktop is a free, simple solution for both Windows and macOS.

Step 1: Install Chrome and the Remote Desktop Extension

  1. On both computers, open Chrome.

  2. Visit https://remotedesktop.google.com.

  3. Click on “Remote Access”, then Download to install the extension.

Step 2: Set Up Remote Access

  1. On the host computer, under “Set up remote access,” click Turn On.

  2. Choose a name for the device.

  3. Set a PIN with at least 6 digits for security.

Step 3: Access the Host Computer

  1. From the client computer, go to the same Chrome Remote Desktop site.

  2. Sign in with the same Google account used on the host computer.

  3. Select the device and enter the PIN to connect.

No port forwarding or firewall changes are needed, making this a great choice for beginners.

Method 3: Using TeamViewer or AnyDesk

These third-party tools are popular for their ease of use and robust feature sets.

Step 1: Install the Software

  1. Download and install TeamViewer or AnyDesk on both the client and host machines.

Step 2: Configure Access

  • TeamViewer provides a unique ID and password for each machine.

  • AnyDesk uses an address or alias for quick connection.

You can also set up unattended access with a permanent password for regular use.

Step 3: Connect Remotely

  1. On the client computer, enter the host's ID/address.

  2. Enter the password or accept the connection on the host.

  3. Start controlling the computer remotely.

Both platforms offer cross-platform support and mobile apps.

Security Considerations

When accessing a computer over the internet, security is critical. Here are some best practices:

  • Use Strong Passwords – Avoid simple or default credentials.

  • Enable Two-Factor Authentication (2FA) – Many platforms support 2FA.

  • Avoid Public Wi-Fi – If unavoidable, use a VPN.

  • Keep Software Updated – Patch remote access tools regularly.

  • Limit Access – Only allow remote access when needed.

If using RDP over the internet, strongly consider setting up a VPN or Remote Desktop Gateway to shield the connection from direct internet exposure.

Use Cases of Remote Desktop Access

  • Remote Work – Access your office computer from anywhere, whether traveling or working from home.

  • IT Support – Troubleshoot and resolve issues remotely, without requiring physical presence.

  • File Access – Retrieve documents or media files from your home PC.

  • Server Management – Control servers or headless systems remotely.

  • Education – Tutors and educators can provide remote instruction or assistance.

Conclusion

Remote desktop access over the internet is a powerful capability that brings flexibility and convenience to users across different industries. Whether you're using built-in tools like Microsoft Remote Desktop or opting for third-party solutions like Chrome Remote Desktop or TeamViewer, the key is to set it up properly and securely.

By following the steps outlined above, you can reliably and safely connect to any computer from virtually anywhere in the world—just make sure to protect yourself and your data along the way.

Need help choosing a remote access tool?

  • Beginners: Try Chrome Remote Desktop

  • Businesses: Use Microsoft Remote Desktop with a VPN

  • IT Support: Opt for TeamViewer or AnyDesk

Remote access doesn’t have to be complicated—just secure, consistent, and efficient.
