Does Windows still use NetBIOS?
NetBIOS (Network Basic Input/Output System) was created in the early 1980’s, but is surprisingly still alive and well on many networks today. Microsoft Windows still uses it for its name resolution function (often by default), when DNS is not available.
How do I enable NetBIOS on Windows 10?
Right-click on Local Area Connection and select Properties. Click Internet Protocol (TCP/IP) and select Properties. Click Advanced > WINS. From the NetBIOS setting area, ensure that Default or Enable NetBIOS over TCP/IP are selected.
How do I disable NetBIOS in Windows 10?

- Open network connection properties.
- Select TCP/IPv4 and open its properties.
- Click Advanced, then go to WINS tab and select Disable NetBIOS over TCP.
- Save the changes.
Is NetBIOS over TCP IP needed?
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. NetBIOS isn’t used in Server 2008 R2 clusters. To disable NetBIOS over TCP/IP, access the IPv4 properties of your network adapter.
Is NetBIOS needed anymore?
“NetBIOS” the protocol (NBF) is gone, long replaced by NBT, CIFS, etc. “NetBIOS” as part of the name of other things still exists. Windows still has an embedded WINS server, even if there’s no dedicated WINS server on the network. NETBIOS over TCP/IP is most certainly still supported in Windows Vista and above.
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.
How do I activate NetBIOS?
To enable NetBIOS Over TCP/IP on Windows XP and Windows 2000:
- Open the Network Connections folder.
- Right click the local area network connection and click Properties.
- Double click Internet Protocol (TCP/IP).
- Click Advanced.
- Click WINS.
- Click the Enable NetBIOS Over TCP/IP button.
How do I find my NetBIOS name Windows 10?

What does NetBIOS do?
NetBIOS is an abbreviation of Network Basic Input/Output System. The primary purpose of NetBIOS is to allow applications on separate computers to communicate and establish sessions to access shared resources, such as files and printers, and to find each other over a local area network (LAN).
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.
How do I completely disable NetBIOS?

How does NetBIOS over TCP IP work?
When a network is functioning normally, NetBIOS over TCP/IP (NetBT) resolves NetBIOS names to IP addresses. It does this through several options for NetBIOS name resolution, including local cache lookup, WINS server query, broadcast, LMHOSTS lookup, Hosts lookup, and DNS server query.
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.
Is NetBIOS a protocol?
NetBIOS is a non-routable OSI Session Layer 5 Protocol and a service that allows applications on computers to communicate with one another over a local area network (LAN).
What NetBIOS over TCP IP?
NetBIOS over TCP/IP provides the NetBIOS programming interface over the TCP/IP protocol. It extends the reach of NetBIOS client and server programs to the wide area network (WAN). It also provides interoperability with various other operating systems.
