4. **Command-Line Interface (CLI) Tools (SSH):** For advanced users, Secure Shell (SSH) allows you to remotely access and control a computer’s command line interface. This is particularly useful for server management.
## 1. Using Windows Remote Desktop
Windows Remote Desktop is a powerful tool built into Windows, but it’s only available on Professional, Enterprise, and Server editions. If you have Windows Home, you’ll need to upgrade to a Pro version or use a third-party solution. Here’s how to set it up:
**Step 1: Enable Remote Desktop on the Host PC (the computer you want to control)**
* **Open System Properties:**
* Press the Windows key + `Pause/Break` key (or search for “System” in the Start menu and click “System”).
* Click on “Remote settings” on the left-hand side.
* **Enable Remote Desktop:**
* In the “Remote” tab, under “Remote Desktop,” select “Allow remote connections to this computer.” A warning may appear, click “OK” to proceed. For enhanced security, select “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended).”
* **Select Users (Optional):**
* Click “Select Users…” to grant specific user accounts permission to access the computer remotely. Add the user accounts that you want to allow access. These user accounts must have a password set.
* **Confirm Settings:**
* Click “Apply” and then “OK” to save the changes.
**Step 2: Find the Host PC’s IP Address**
To connect to the host PC, you need its IP address. There are several ways to find it:
* **Using Command Prompt:**
* Press the Windows key, type “cmd,” and press Enter to open the Command Prompt.
* Type `ipconfig` and press Enter.
* Look for the “IPv4 Address” under your network adapter (e.g., Ethernet adapter or Wireless LAN adapter). This is your computer’s local IP address within your network.
* **Using Settings:**
* Press the Windows key, type “Settings,” and press Enter.
* Click on “Network & Internet.” Choose either Ethernet or Wi-Fi on the left, depending on your connection type.
* Click on your network connection. The IP address will be listed near the bottom.
* **Using a Website:**
* If you are outside your local network you’ll need to find the public IP address. Use a website such as whatismyip.com to determine your public IP. Note this is less ideal as public IPs can change unless you have a static IP address with your ISP.
**Step 3: Configure Your Router (if connecting from outside your local network)**
If you want to connect to your PC from outside your local network (e.g., from a different internet connection), you need to configure your router to forward incoming Remote Desktop traffic (port 3389) to your PC’s local IP address. This is called port forwarding.
* **Access Your Router’s Configuration Page:**
* Open a web browser and type your router’s IP address into the address bar. This is usually something like `192.168.1.1` or `192.168.0.1`. You may need to consult your router’s documentation or contact your internet service provider (ISP) to find the correct address and login credentials (username and password).
* **Find the Port Forwarding Section:**
* The location of the port forwarding section varies depending on your router’s manufacturer. Look for options like “Port Forwarding,” “Virtual Servers,” “NAT Forwarding,” or similar.
* **Create a New Port Forwarding Rule:**
* Enter the following information:
* **Service Name/Description:** A descriptive name, such as “Remote Desktop.”
* **Port Range:** Enter `3389` as both the starting and ending port. (The default Remote Desktop port is 3389.)
* **Local IP Address:** Enter the local IP address of your host PC (the one you found in Step 2).
* **Protocol:** Select “TCP.” Some routers require you to choose both TCP and UDP; if this is the case, create two separate rules, one for TCP and one for UDP with port 3389.
* Save the rule.
**Security Warning:** Exposing port 3389 directly to the internet can be a security risk. Consider changing the default Remote Desktop port to a different, less common port to reduce the risk of brute-force attacks. To do this, you’ll need to edit the Windows Registry (regedit). Search online for instructions on changing the Remote Desktop port.
**Step 4: Connect to the Host PC from the Client PC (the computer you’re using to connect)**
* **Open Remote Desktop Connection:**
* On the client PC, press the Windows key, type “Remote Desktop Connection,” and press Enter.
* **Enter the IP Address:**
* In the “Computer” field, enter the IP address of the host PC. If you are connecting from within the same local network, use the local IP address. If you are connecting from outside the network, use your public IP address.
* If you changed the default Remote Desktop port, append the port number to the IP address, separated by a colon (e.g., `your_public_ip:new_port_number`).
* **Connect:**
* Click “Connect.” You may be prompted to enter your username and password for the host PC. Use the credentials of an account that has remote access permission (as configured in Step 1).
* **Security Warning:**
* If a security certificate warning appears, verify that you are connecting to the correct computer and click “Yes” to continue.
* **Start Using the Host PC:**
* You should now be connected to the host PC and be able to control it remotely. Everything you do on the client PC will be mirrored on the host PC.
**Step 5: Disconnect the Remote Desktop Session**
When you’re finished, you can disconnect the Remote Desktop session in several ways:
* **Close the Remote Desktop window:** This will disconnect the session, but the programs and applications on the host PC will continue running. The user will be locked out of the current session on the host machine until you disconnect, or log off the session.
* **Log off the session:** Click on the start menu, select user icon, and then select “Sign out”. This will close all programs and applications on the host PC.
