NetBIOS Name Overview

A computer in the network can be named after the NetBIOS and DNS two naming, and in the NetBIOS standard, a name with a length of not more than 16 characters is used to uniquely identify each network resource to identify the resource or service type. In the actual work. The computer name, workgroup name, or domain name that you see through my Network Places in the Windows operating system is the NetBIOS name.

The working process of NetBIOS

When you use NetBIOS names on your network, the basic work process includes the registration, release, and query of NetBIOS names. Registration is performed dynamically at the time the computer starts up, the service starts, or the user logs on. The NetBIOS name is released when the computer shuts down properly, the service stops properly, or the user exits normally. If a computer attempts to access another computer through a NetBIOS name, a NetBIOS name query is required to enable normal communication, and the registration and release of the NetBIOS name is essentially a service for name queries. In 2003, you can implement NetBIOS name registration, release, and query based on the NetBEUI and TCP/IP two protocols.

1, based on NetBEUI protocol support NetBIOS

The NetBEUI protocol, which IBM introduced and developed in 1985, lacks routing and network-layer addressing capabilities. All communication can only be done by broadcasting messages, so it can only be applied to small workgroups or LANs, because the NetBEUI information has only the Data link layer MAC address and does not require additional network addresses and the end of the network layer. If you are using only NetBIOS names to communicate on your network, you can simply deploy the NetBEUI protocol without deploying the TCP/IP protocol. In the current network, the NetBEUI protocol is basically not used to NETBIOS. 2003 no longer provides it, the replacement is the TCP/IP protocol.

2, based on the TCP/IP protocol support NetBIOS

Implemented through its components. is enabled by default in 2003.

NetBIOS name resolution

When using "NetBIOS on TCP/IP" to support NetBIOS, you need to resolve the NetBIOS to an IP address and then communicate through an IP address, and in WIN2003, NetBIOS parsing can be done in a number of ways. The first 3 of these are standard NetBIOS name resolution methods, and the latter are Microsoft's proprietary NetBIOS name resolution methods.

1. Resolve NetBIOS name through NetBIOS name resolution cache

The NetBIOS name cache holds the recently queried NetBIOS name of the local host and uses Nbtstat to view information about the NetBIOS name. NetBIOS name resolution is the primary parsing method.

2. Resolve NetBIOS names by sending broadcast messages

When a host needs to resolve a NetBIOS name, it can send a broadcast message to the network containing the NetBIOS name to resolve, and all hosts on the network will receive the broadcast message and check whether the registered NetBIOS name matches the NetBIOS name of the broadcast message. This way of parsing encounters two problems: broadcasts will interfere with each node on the network. Routers typically do not forward broadcasts, so only ntbios names on the local network can be resolved.
