The VM can now communicate with other legacy NetBEUI devices on the same physical network (bridged mode) or with other VMs (internal network).
If you are trying to connect a modern Windows 7, 10, or 11 PC to a vintage CNC machine, an old laboratory device, or a legacy file server that strictly requires NetBEUI, you will face an immediate roadblock: Windows simply will not recognize the protocol.
Windows 7, a widely used operating system even years after its release, does not natively support NETBEUI. Microsoft ended mainstream support for Windows 7 in January 2020, but it still receives extended support until January 2025. For those who need to run Windows 7 and require NETBEUI support, there are workarounds.
If the legacy equipment absolutely requires the NetBEUI stack, use a Virtual Machine (VM) running Windows XP. Install Oracle VM VirtualBox. Create an XP VM. Bridge the network adapter in VirtualBox.

However, you can run NetBEUI on these OSes in specific, limited ways. This guide covers the only two working methods.
For advanced users, setting up a dedicated server to act as a translation layer can be an effective long-term solution.
While Microsoft stopped including NetBEUI files after Windows Server 2003, users typically "fix" this by manually porting files from an older Windows XP installation media: : nbf.sys is copied to %SYSTEMROOT%\System32\Drivers . netnbf.inf is copied to %SYSTEMROOT%\Inf (a hidden folder).

As you weigh your options, remember that technology evolves by leaving old standards behind—and NetBEUI is no exception. The solutions outlined in this guide will serve you well today, but the most future-proof decision you can make is to gradually migrate away from NetBEUI dependency whenever possible. Your network will be faster, more secure, and far more compatible with the modern world as a result. The VM can now communicate with other legacy
When using third-party solutions, proceed with caution, and ensure thorough testing in a controlled environment.
Proceed with extreme caution. Most such drivers are either for unrelated hardware, outright malware, or simply do not work as advertised. The safest approach is to stick with the legitimate alternatives described above.
For industrial or business environments where a virtual machine is not appropriate (e.g., when dealing with physical serial or parallel connections), consider using a dedicated bridge device.
If your goal is to run vintage DOS-era games or software that requires NetBEUI for multiplayer or network connectivity on Windows 10 or 11, standard DOSBox will not suffice. However, (an active fork of the project) features native network emulation capabilities. Download and install DOSBox-X . Open the dosbox-x.conf configuration file.

What are you trying to connect to?
In the world of computer networking, protocols come and go, but few have the staying power of NetBEUI (NetBIOS Extended User Interface). Introduced by IBM in 1985, this protocol was once the standard for file and printer sharing in small networks running MS-DOS, Windows for Workgroups, and Windows 9x. Its primary advantages were its simplicity and speed, as it was a lightweight, non-routable protocol designed for a single network segment.
This is perhaps the most critical real-world use case. Countless industrial machines—including CNC routers, printing presses, medical devices, and manufacturing equipment—were built in the 1990s and early 2000s with embedded Windows NT or Windows 2000 systems that use NetBEUI for file sharing and control. Upgrading these machines is often prohibitively expensive or simply impossible. As noted in an October 2023 discussion on Linus Tech Tips, "It's an old prepress computer running Windows Server 2000 and I’ve narrowed it down to Windows 10’s lack of support for NetBEUI protocol". In situations like these, getting NetBEUI working on a modern Windows machine is not a hobby—it's a business necessity.
