What NetBIOS is used for?
NetBIOS (/ˈnɛtbaɪɒs/) is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol.
Is NetBIOS obsolete?
Amazingly, NetBIOS is actually still used in the trust creation process, even though Microsoft has officially “deprecated” NetBIOS in versions of Windows from 2000 on. So if you disable NETBIOS on your domain controllers, you won’t be able to establish a forest trust between two Windows Server 2003 forests.
Should I disable NetBIOS?
Yes. To improve performance, it’s recommended that you disable NetBIOS over TCP/IP on your cluster network NIC and other dedicated-purpose NICs, such as for iSCSI and Live Migration.
What is the difference between NetBIOS and DNS?
As has been shown above the main difference between DNS and NetBIOS is the availability of DNS being only available when there is a connection to the internet and the name is registered in the computer. NetBIOS on the other hand is always available to the machines connecting directly to it.
How do I disable NetBIOS?

Ports 137, 138, and 139 are used by NetBIOS, which does not support IPv6. CIFS is required for Windows file service. You can disable CIFS by issuing the cifs terminate command on your storage system console.
Where is NetBIOS used?

Does Active Directory use NetBIOS?
In particular every AD Domain also has a NetBIOS name along with its traditional DNS name. And every computer in your domain will also have a NetBIOS name (even if you turn the NetBIOS names service off).
Is NetBIOS a security risk?
Vulnerabilities in Windows Host NetBIOS to Information Retrieval is a Low risk vulnerability that is also high frequency and high visibility. This is the most severe combination of security factors that exists and it is extremely important to find it on your network and fix it as soon as possible.
Why is NetBIOS bad?
There are quite a few reasons why NetBIOS is bad for your network. NetBIOS is an inneficient protocol. It is very chatty with lots of broadcasts. When used with its defaults settings, it can be used by the bad guys to gather information about your network and users.
Is NetBIOS needed for SMB?
SMB does rely on NetBIOS for communication with devices that do not support direct hosting of SMB over TCP/IP. NetBIOS is completely independent from SMB. It is an API that SMB, and other technologies can use, so NetBIOS has no dependency to SMB.
