If you’re setting up a network environment where you need to transfer files quickly and efficiently, a TFTP server on Windows is your answer. TFTP (Trivial File Transfer Protocol) is lightweight, fast, and perfect for booting devices, transferring firmware, or moving files across your network without the overhead of FTP or HTTP. The good news? Getting one running on Windows is straightforward, and you’ve got solid options that range from simple and free to feature-rich enterprise solutions.
This guide walks you through downloading, installing, and configuring a TFTP server on Windows, covering the most practical tools available so you can get up and running in minutes. We’ll explore the following sections to help you choose and deploy the right solution for your needs:

Why TFTP and When You Need It
TFTP is the minimalist’s file transfer protocol. It strips away authentication, encryption, and complex features to deliver pure speed and simplicity. You’ll find TFTP servers essential in scenarios like:
- Network device provisioning — routers, switches, and firewalls often boot via TFTP
- Firmware updates — embedded systems and network hardware rely on TFTP for quick transfers
- PXE boot environments — network booting systems need TFTP to load initial files
- Lab and testing environments — when you need no-frills file sharing on a local network
Unlike FTP, TFTP doesn’t require user authentication, making it ideal for automated processes and device communication. On Windows, running a TFTP server means your devices can pull files from your machine without complex setup.
Popular TFTP Server Options for Windows
You’ve got several solid choices when it comes to TFTP servers on Windows. Here are the most reliable:
Tftpd64 — The Go-To Free Option
Tftpd64 is the most popular free TFTP server for Windows. It’s lightweight, easy to configure, and works reliably for most use cases. It also includes DHCP and DNS server capabilities if you need them, making it a multi-purpose tool for network environments.
SolarWinds TFTP Server
SolarWinds offers a more polished, enterprise-focused TFTP server with better logging, monitoring, and support. It’s free to download and ideal if you want professional-grade features without the complexity of larger solutions.
3CDaemon
An older but still functional option, 3CDaemon combines TFTP, FTP, and Syslog services in one package. It’s lightweight and works well if you need multiple protocols on the same machine.
For most users, Tftpd64 is the best starting point. It’s actively maintained, has a straightforward interface, and requires minimal configuration.
How to Download and Install Tftpd64
Step 1: Download Tftpd64
- Visit the official Tftpd64 website or a trusted software repository
- Look for the latest version (available in both installer and portable versions)
- Choose the installer version for a standard Windows installation, or the portable version if you want to run it without installation
- Click download and save the file to your computer
Step 2: Install Tftpd64
- Double-click the downloaded installer file
- Follow the installation wizard — default settings work fine for most users
- Choose your installation directory (Program Files is standard)
- Complete the installation and launch the application
If you downloaded the portable version, simply extract the ZIP file and run the executable directly — no installation needed.
Step 3: Configure Your TFTP Root Directory
When Tftpd64 launches, you’ll see a simple interface. The most critical step is setting your TFTP root directory — this is where files will be stored and retrieved from.
- In the main window, look for the folder icon or “Browse” button
- Select or create a folder where you want to store TFTP files (e.g., C:\TFTP)
- Place any files you want to serve in this directory
- Confirm the selection
Everything in this folder becomes accessible to clients requesting files via TFTP. Keep it organized and only include files you intend to share.
Step 4: Start the Server
- Look for a “Start” or “Listen” button in the Tftpd64 interface
- Click it to activate the TFTP server
- You should see a status message indicating the server is listening (typically on port 69, the standard TFTP port)
The server is now running and ready to handle file transfer requests from your network.
Installing SolarWinds TFTP Server (Alternative)
If you prefer a more polished interface, SolarWinds TFTP Server is worth considering:
- Download from SolarWinds’ website (it’s free)
- Run the installer and follow the setup wizard
- During installation, you’ll be prompted to set the TFTP root directory — choose your preferred location
- Complete installation and open the application
- The interface provides clearer logging and monitoring than Tftpd64, showing each file transfer in real-time
- Click “Start Service” to begin accepting connections
SolarWinds is particularly useful if you’re managing multiple devices or need detailed transfer logs for compliance or troubleshooting.
Essential Configuration Tips
Firewall Settings
Windows Firewall may block TFTP traffic by default. To allow it:
- Open Windows Defender Firewall with Advanced Security
- Click “Inbound Rules” and create a new rule
- Select “Port” and specify UDP port 69
- Allow the connection and apply the rule
Alternatively, most TFTP server applications will prompt you to add a firewall exception during installation.
Network Permissions
Ensure your Windows user account has read/write permissions on the TFTP root directory. Right-click the folder, select Properties, go to Security, and verify your user has appropriate permissions.
Testing Your Server
To verify your TFTP server is working, use a command-line tool on another machine on your network. On Windows, you can use the TFTP client built into Windows (if enabled) or download a dedicated TFTP client to test file transfers.
Running TFTP as a Windows Service
For a more permanent setup, you can configure your TFTP server to run as a Windows service, meaning it starts automatically when Windows boots.
Tftpd64 includes this option in its settings menu. SolarWinds TFTP Server also offers service installation. This is especially useful for servers or always-on machines where you want TFTP available without manually starting the application.
Security Considerations
TFTP lacks built-in security features, so keep these points in mind:
- Network isolation — only run TFTP on trusted internal networks
- File selection — only place files in the TFTP directory that you intend to share
- Access logging — monitor transfer logs to catch unauthorized access attempts
- Firewall rules — restrict TFTP to specific IP ranges if possible
TFTP is designed for controlled environments like labs, local networks, and device provisioning — not for exposing files to the internet.
Troubleshooting Common Issues
Server starts but clients can’t connect: Check Windows Firewall rules and ensure UDP port 69 is open. Verify the server is actually listening by checking the application status.
Files not appearing in transfers: Confirm files are in the correct TFTP root directory and that file permissions allow reading.
Slow transfers: TFTP is inherently slow on high-latency networks. For large files, consider FTP or HTTP instead. TFTP shines with small firmware images and boot files.
Port 69 already in use: Another service may be using the standard TFTP port. Check your application settings to use an alternative port, though this requires clients to specify the non-standard port.
Get Your TFTP Server Running
Whether you choose Tftpd64 for simplicity or SolarWinds for enterprise features, you’re looking at a 5-10 minute setup. Download, install, point to your file directory, and start serving. TFTP is one of those “set it and forget it” tools that just works when configured properly.
