In 1983, IBM's (and Sytek's) design goal of Network Basic Input/Output System (NetBIOS), was to build a small and fast protocol that would allow for human-assigned names of devices, such as 'MyComputer', that are easier to remember than a complex numbering scheme. NetBIOS is effectively IBMs API for PCs to access LAN facilities. [ Netbios is not supported on Windows Vista, Windows Server 2008, and subsequent versions of the operating system] The Netbios function interprets and executes the specified network control block (NCB). The Netbios function is provided primarily for applications that were written for the NetBIOS interface and need to be ported to Windows. 220.127.116.11 workgroup. The workgroup parameter sets the current workgroup where the Samba server will advertise itself. Clients that wish to access shares on the Samba server should be on the same NetBIOS workgroup. Microsoft's implementation of NetBIOS Over TCP/IP (NetBT) provides the NetBIOS programming interface over the TCP/IP protocol, extending the reach of NetBIOS client and server programs to TCP/IP networks and providing interoperability with other operating systems.

From Wikipedia, the free encyclopedia NetBIOS over TCP/IP (NBT, or sometimes NetBT) is a networking protocol that allows legacy computer applications relying on the NetBIOS API to be used on modern TCP/IP networks. NetBIOS was developed in the early 1980s, targeting very small networks (about a dozen computers).
NetBIOS aliases are alternative names for your CIFS server that SMB clients can use when connecting to the CIFS server. Configuring NetBIOS aliases for a CIFS server can be useful when you are consolidating data from other file servers to the CIFS server and want the CIFS server to respond to the original file servers' names. In order to reach a workstation through WINS name resolution there has to be a WINS server shared on both networks workgroups if you will. NetBIOS over TCP is a feature that is enabled on the actual network settings on the PC and not on the firewall. "Could not connect.

I have a command that can disable this remotely on all AD devices, but the issue is that only PC's connected to the network at the time of me running the script will respond. NetBIOS name resolution to an IP can happen via broadcast communications, using a WINS server, or using the LMHOSTS file. The Attack The main issue with these protocols is the inherent trust the victim computer assumes with other devices within its segment of the network. I have a pfSense applicance running version 2.x.
