When it comes to transferring small files across enterprise-scale networks, TFTP (Trivial File Transfer Protocol) servers are an administrator’s best-kept secret. In the eyes of many people, TFTP servers have become outdated in the fast-moving world of protocols. They aren’t particularly glamorous and they don’t have any grand functions. However, if you want to push firmware upgrades to devices throughout your network, a TFTP server has an essential place in your network management toolkit.

What is TFTP?
Before we get to the best TFTP servers themselves, it is important to get to grips with what TFTP is. TFTP is a protocol used for small file transfers and doesn’t require any authentication. It’s essentially a less complex version of FTP. TFTP servers are found in devices like routers and mobile phones. TFTP is used to transfer files, backup network configurations, and boot PCs without a disk.
You’re most likely to encounter TFTP servers on Linux but they can be found on Windows and Mac as well. One of the biggest drawbacks of TFTP is that it doesn’t have any access privileges in place, so anyone can access a TFTP server unless you use an external firewall or other third-party device. This makes it less secure than other protocols like FTP and SCP.
When you use a TFTP protocol you’re launching a request to read or write a file and requesting a connection from the server.
The Best TFTP Servers for Windows
Now we’ve taken you through what TFTP is and what it is used for, it’s time to look at TFTP server tools themselves. Below we look at some of the best TFTP servers available and provide you with an overview to help you find the best solution for your organization.
Our methodology for selecting the best TFTP server for Windows

TFTP Servers: Still Relevant
Despite TFTP’s basic nature, Network administrators will always have a place for quality TFTP servers like those above. TFTP Servers like SolarWinds TFTP Server and WinAgents are our top picks for enterprises looking for solutions that are simple to deploy and easy to scale. If you need to install firmware across a substantial network then we highly recommended downloading a TFTP server to save you a ton of time.
Don’t make the mistake of thinking that TFTP has had its time. While it may not be the most glamorous, it does have an integral place in making your network maintenance much more efficient. There are plenty of resources out there to provide you with more information on TFTP, so don’t hesitate to experiment with a new tool. Below we’re going to provide you with a little more information on what TFTP is used for, its limitations and a guide to setting up a TFTP server.
What is TFTP Used For?
Generally speaking, TFTP is primarily used to transfer small files across LAN networks using UDP. It doesn’t require much in the way of network resources. It’s a relatively painless way to send files or firmware updates to devices throughout the network. In addition to conserving network resources, this also makes it much easier to update device firmware.
Attempting to manually upgrade the firmware of hundreds of different devices on an ongoing basis is extremely inefficient. A TFTP server allows you to push firmware updates straight to these devices from a centralized location. This means you don’t have to spend hours carrying out one task because you can use TFTP to automate the entire process.
Why Do I Need to Use TFTP?
There are many reasons to use TFTP, one of the main reason is to conduct firmware updates on an enterprise-scale network. TFTP is preferable to FTP and HTTP because TFTP is simple to setup. You don’t need any special parameters or configurations, so your interaction with the TFTP server is kept relatively simple. Ultimately, there’s very little that can go wrong. Using TFTP takes up very little memory.
The reason why network administrators use TFTP over FTP is that it doesn’t require user credentials in order to operate. We’ve provided a brief list of reasons why you might need to use TFTP:
- To transfer files across a network
- To boot devices without using a hard drive
- To backup network configurations
- To save IOS images
- To backup configuration files from your computer
TFTP’s Limitations
Although TFTP is useful for some tasks, it receives a lot of criticism from the IT community on account of its weaknesses. This is mainly because TFTP is unauthenticated and insecure. This is an inherent part of the protocol and it is simply outperformed by FTP in most cases. TFTP was designed to transfer data with minimal effort and restrictions. The negative side to this is that anyone can access your configurations at will. There is nothing to stop a user from uploading malicious configurations or deleting your current ones. As such this isn’t the right protocol for transferring confidential files.
Yet TFTP’s problems don’t end there. Even though TFTP is good for transporting lightweight files, it struggles with larger files. In many cases you’re better off transporting files through the use of FTP. Today even HTTP can be used to push firmware straight to VOIP phones. Despite TFTP’s limitations, it does still have a place in most modern network environments.
How to set up a TFTP Server
In order to start using a TFTP server you first need to choose a software platform (we have listed some of the best options below). Once you’ve selected your software, the first thing you need to do after installation is create an inbound/outbound rule. Click on Control Panel > System and Security > Windows Firewall and Advanced Settings. In the sections denoted Inbound and Outbound you want to make sure that “Simple TFTP server” is listed in both.
Once this is done you need to find a root folder to use; the default will be something like:
C:\Program Files\YourTFTPserver\secure
You can specify an alternative folder if you wish. This will be where you store all transferable files and the sole location your TFTP server operates through. As a general tip, you want to make sure you stick to using single files in this folder.
How to manage network devices with TFTP
You can schedule transfer commands with some TFTP tools and you can also set up scripts to recursively send out configuration files to all devices. However, you need to create different source directories on your TFTP server host for each device type, make and model.
There are a couple structural considerations that you have to take care of when you set up a TFTP server as a rudimentary configuration manager.
- Create a directory for each device type/make/model combination
- Create three subdirectories for configuration image backup, default configuration, and current status
When you install a new device, make sure to copy off its configuration into the default configuration directory that you created on the TFTP server host for that device type/make/model.
In order to manage the configuration of each device, you will need to implement the following steps:
- Create a policy for the device’s settings.
- Backup the device’s current status by transferring an image from the device to the TFTP server host.
- Send out the adjusted configuration image.
- Test the device’s new settings.
- Optionally rollback to previous configuration by sending stored backup by TFTP
- Periodically copy the current device status.
- Compare current configuration image file with the policy configuration file
- Reset the device with the policy configuration file if divergence detected.
Schedule the configuration checks to run periodically either through a shell script or by utilizing scheduling capabilities of your chosen TFTP server utility.
