What are NetBIOS Names?
A NetBIOS name is an identifier used by NetBIOS services running on a computer. It is combination of a 15 character (byte) name and a 16th character denoting the service. For identifying resources on the NetBIOS network, these names are used. NetBIOS can not do name resolution on the Internet because NetBIOS names are single part names and don't have any hierarchical structure.
The NetBIOS namespace is flat, which means that there are no suffixes added to the NetBIOS name and that two computers cannot have the same NetBIOS name. This means that each NetBIOS name in any one network must be unique.
Characteristics of NetBIOS Names
The characteristics of NetBIOS names are as follows:
- NetBIOS names are used to support services that require NetBIOS. Windows server 2003, Windows 2000, and Windows XP use DNS names for most functions, but a NetBIOS name resolution method must exist on any network with computers that are running earlier versions of windows or for applications that still depend on NetBIOS names.
- A NetBIOS name is an alias that is assigned to a computer by an administrator to identify a NetBIOS server running on TCP/IP host.
- The NetBIOS name does not have to match the host name.
- NetBIOS names are 15 characters or less in length, compared to 255 or fewer characters for DNS host names. The host name and the NetBIOS name on a computer running Windows Server 2003 are generated together. If the host name is more than 15 characters, the NetBIOS name is the first 15 characters of the host name.
- NetBIOS names must be unique on their networks.
- When you start your computer, various services (such as the server service or the workstation service) registers a unique NetBIOS name that is vase on the computer name. The registered name is the 15-character NetBIOS name plus a sixteenth character (byte) that uniquely identifies the server service.
- NetBIOS names are also registered for groups of computers that provide network services. For example, if Mickey.Disney.com is a domain controller, it will register that NetBIOS name, Mickey, and will register names that identify its roles as a domain controller in the Disney domain at the same time. This allows clients to search for all NetBIOS hosts that provide domain controller services in the Disney domain without the client knowing the actual names of the domain controllers.
- A NetBIOS name simplifies the way that a user references other TCP/IP hosts, NetBIOS names are easer to remember than IP addresses.
- A NetBIOS names can be resolved if the name and IP address are stored either in a database on a WINS server or an LMHOSTS file. A broadcast can also resolve a NetBIOS name.
- The nbtstat utility displays the NetBIOS names that NetBIOS services use on your computer.
The NetBIOS name is created while the operating system is being installed. When the computer name is created, the install automatically creates both a host name and a NetBIOS name that are based on the entered computer name.
