In today’s interconnected world, understanding the identity of devices on a network can be crucial for troubleshooting, security, and efficient management. One such identifier is the NetBIOS name, a legacy naming system that remains relevant in many Windows-based networks.
Whether you’re an IT professional seeking to monitor devices, a network administrator aiming to streamline asset management, or simply curious about the names your devices use to communicate, knowing how to find the NetBIOS name is invaluable.
The NetBIOS name serves as a unique identifier for computers within a local area network, allowing them to recognize and interact with each other. While modern networks may rely on DNS for naming, NetBIOS remains embedded in many systems for compatibility and ease of use.
This post will walk you through multiple methods to uncover the NetBIOS name of any device, ensuring you have the right tools and understanding to navigate your network confidently.
Understanding What a NetBIOS Name Is
Before diving into the methods to find the NetBIOS name, it’s important to grasp what it actually represents. NetBIOS stands for Network Basic Input/Output System, a legacy API that allows applications on different computers to communicate over a local network.
Each device on such a network is assigned a unique NetBIOS name, typically limited to 15 characters, which helps identify it within the network environment. This name is crucial for older Windows networking protocols and some network services that depend on legacy systems.
NetBIOS names can be thought of as computer “nicknames” that help devices locate each other without relying solely on IP addresses. This is particularly useful in smaller networks or when DNS is not fully configured.
Understanding this background will make the process of finding the NetBIOS name much clearer and more intuitive.
“NetBIOS names remain a cornerstone for network device identification despite the rise of newer naming conventions.”
Using Command Prompt to Find NetBIOS Name
The Command Prompt is a powerful tool on Windows machines that provides quick access to system information, including the NetBIOS name.
To find your own computer’s NetBIOS name, open the Command Prompt and enter the command “nbtstat -n”. This command displays the NetBIOS name table for the local machine, showing the registered names along with their types.
If you want to find the NetBIOS name of a remote computer on your network, you can use “nbtstat -A [IP address]”. This will query the target system and return its NetBIOS name and other related information.
Steps to Use Command Prompt
- Press Windows + R, type cmd, and hit Enter.
- Type nbtstat -n to see your local NetBIOS names.
- For remote devices, use nbtstat -A [IP address].
- Review the output to find the unique NetBIOS name.
| Command | Purpose |
| nbtstat -n | Displays local NetBIOS names |
| nbtstat -A [IP] | Queries remote machine’s NetBIOS name |
Finding NetBIOS Name Through System Properties
For users who prefer a graphical interface, the Windows System Properties window offers an easy way to locate the NetBIOS name. This method is straightforward and doesn’t require any technical commands.
In Windows, the NetBIOS name typically matches the computer’s hostname, which can be found by navigating to System Properties. This name is what other devices on the network will recognize.
Accessing this information is helpful when you want a quick reference or need to cross-check the device name without opening any command-line tools.
How to Access System Properties
- Right-click on Computer or This PC on the desktop or File Explorer.
- Select Properties from the context menu.
- Look under Computer name, domain, and workgroup settings.
- The displayed Computer name is your NetBIOS name.
“In many cases, the NetBIOS name is identical to the PC’s hostname, making this method the simplest for users.”
Using PowerShell to Retrieve NetBIOS Name
PowerShell, a more advanced scripting environment in Windows, offers commands to extract a variety of network and system details, including the NetBIOS name.
By running specific PowerShell cmdlets, you can quickly obtain the NetBIOS name without manually sifting through the system settings. This method is particularly useful for administrators managing multiple devices or automating network checks.
PowerShell also allows you to query remote systems for their NetBIOS names, similar to the Command Prompt but with more flexibility.
Example PowerShell Commands
- Get-WmiObject Win32_ComputerSystem | Select-Object Name – Retrieves the local computer’s NetBIOS name.
- Invoke-Command -ComputerName [RemotePC] {hostname} – Gets the NetBIOS name of a remote computer.
- Resolve-DnsName [ComputerName] – Can help verify the name resolution on the network.
| Cmdlet | Description |
| Get-WmiObject Win32_ComputerSystem | Fetches local system details including NetBIOS name |
| Invoke-Command -ComputerName | Runs commands on remote machines to get hostname |
Locating NetBIOS Name in Network Settings
Network settings on Windows provide another avenue to find the NetBIOS name, especially useful when troubleshooting connectivity or sharing issues.
The NetBIOS name is often displayed in the network adapter’s detailed settings or within advanced sharing settings. This is where you can also enable or disable NetBIOS over TCP/IP, an important setting for network communication.
Exploring these settings not only reveals the NetBIOS name but also gives insight into how your device interacts with other computers in your network.
Steps to Check Network Settings
- Open Control Panel and go to Network and Sharing Center.
- Click on Change adapter settings on the left side.
- Right-click your active network adapter and select Properties.
- Choose Internet Protocol Version 4 (TCP/IPv4), then click Properties.
- Click Advanced, then go to the WINS tab.
- Here, you can see if NetBIOS over TCP/IP is enabled and the NetBIOS name info.
“Enabling NetBIOS over TCP/IP is essential for legacy applications relying on NetBIOS names.”
Using Network Scanning Tools to Identify NetBIOS Names
For those managing larger networks, manual methods can become tedious. Network scanning software offers an efficient way to detect all devices and their NetBIOS names.
Tools like Nmap or specialized Windows utilities can scan IP ranges and report NetBIOS names along with other device information. These tools are invaluable for network administrators performing audits or security checks.
Using these tools requires some technical knowledge but rewards with comprehensive network visibility.
Popular Network Scanning Tools
- Nmap – Open-source scanner that supports NetBIOS name discovery.
- Advanced IP Scanner – User-friendly tool popular for Windows users.
- SoftPerfect Network Scanner – Offers detailed info including NetBIOS names.

Checking NetBIOS Name on Mac and Linux Systems
While NetBIOS is primarily a Windows protocol, Mac and Linux systems can also interact with Windows networks and may have NetBIOS names configured.
On Mac, you can check the NetBIOS name by looking at the Sharing preferences. Linux users can use Samba tools like smbclient or nmblookup to query NetBIOS names on the network.
This cross-platform capability is essential in mixed-network environments where devices from different operating systems communicate.
Commands and Methods for Mac/Linux
- On Mac: Go to System Preferences > Sharing; the Computer Name is often the NetBIOS name.
- On Linux: Use nmblookup -A [IP address] to query NetBIOS name.
- Use smbclient -L [hostname or IP] to list shares and names.
“NetBIOS names remain relevant beyond Windows, especially in mixed OS networks.”
Common Issues and Troubleshooting When Finding NetBIOS Names
Sometimes, locating a NetBIOS name isn’t straightforward. Network configurations, firewalls, or disabled services can block NetBIOS name resolution.
Understanding common pitfalls can save time and prevent frustration. For example, if a device doesn’t respond to nbtstat queries, it may have NetBIOS over TCP/IP disabled or be outside your subnet.
Checking network discovery settings and ensuring the computer is powered on and connected are basic steps that often resolve most issues.
Tips to Troubleshoot
- Verify that NetBIOS over TCP/IP is enabled on the target device.
- Ensure network discovery and file sharing are turned on.
- Check firewall settings that may block NetBIOS traffic.
- Confirm the device is reachable via ping before querying NetBIOS name.
