You might find that a critical application relies on NetBIOS (with no alternative currently available) in which case, you must continue to use WINS.

Windows Internet Name Service (WINS) provides a dynamic replicated database service that can register and resolve NetBIOS names to IP addresses that are used on your network. character can be used in host names.

In this framework, the naming system is called the domain namespace and is structured similarly to a directory tree on a disk drive. You can find all of the documentation for WINS at Windows Internet Name Service in the Windows Server TechCenter. ■ Computer name A computer name is just that, the name you give your computer. Applies To: Windows Server 2003, Windows Vista, Windows XP, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2012, Windows 8. Let's take a moment to go through some of these to help answer any questions you might have. A NetBIOS name can be l6 characters long, but in Windows, the sixteenth character is reserved for various NetBIOS functions.

In this system, the domain namespace begins at the root, which is unnamed and is identified by ". "As it expands, there are more and more branches to the tree and each node creates a unique name. Already a member? ■ Host name This term originates in the mainframe and UNIX world. WINS primarily supports clients that run early versions of the Windows operating system and applications that require NetBIOS.

The documentation for WINS has not been updated for this version of Windows. Although host names are resolved to IP addresses as are NetBIOS names, the resolution process is different—do not confuse these two types of names.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. NOTE: Before you turn off WINS/NetBT name resolution, verify that you do not need to use WINS or earlier NetBT-type applications for this network connection.


Host names must be resolved via host name resolution, which is accomplished via a HOSTS file or via DNS servers, requesters, and resolvers (you'll learn more about this later in this chapter). Notice that WINS is a dynamic replacement for the LMHOSTS file.

In the command prompt window, type hostname, then press Enter.

The NetBIOS construction is a flat naming system.This means that only one computer can have a particular name, which must be unique on that network (or on any network to which that network is attached). If you're on a network, this name must be unique.

For more information, see Microsoft Knowledge Base article 122900. Write For Us It was created in 1983 by Sytek and is often used with the NetBIOS over TCP/IP protocol.

It is a flat naming system with names that cannot exceed 16 characters. Close this window and log in. ■ NetBIOS name In a Windows-based computer, the name you see listed on the Computer Name tab of the My Computer properties is the NetBIOS name.This name can be up to 15 characters long (in Microsoft operating systems) and is used to identify the computer on the network. ■ Nickname A nickname is an alternate name given a host name. But it can use the nickname rosie2.You'll learn more on this topic throughout this chapter.

The name type is shown with the hexadecimal (hex or h) suffix. WINS is used in case we have machines that use NetBios names like pre-2000 OS, WINS is limited to Microsoft products only but DNS is open and standard. Option 044 = Specifies a list of IP addresses for NetBIOS name servers (NBNS).

to distinguish branches or nodes of the name within a hierarchy.

| Put the money that you were going to pay the PC Tech in your own pocket. Several of the more common NetBIOS suffixes are shown here. to Then click the Computer Name tab to display (or change) your computer name. When NetBIOS name resolution occurs, the computer name (NetBIOS name) is mapped to an IP address. The dot character is interpreted as a delimiter and can be used in Fully Qualified Domain Names (FQDN). Click Disable NetBIOS over TCP/IP.
Hosts file or LMHosts file, whatÆs the difference? The NetBIOS Name Service is part of the NetBIOS-over-TCP protocol suite, see the NetBIOS page for further information.. NBNS serves much the same purpose as DNS does: translate human-readable names to IP addresses (e.g.

If you're not on a network, this name can be just about anything you choose.You can configure alternate names on the Computer Name tab by clicking More and entering your particular data. Case is not relevant, thus there is no difference between the names SERVER, SERver, and server. A host name can be up to 255 characters long and can contain alphanumeric characters and the hyphen symbol (-). Technically, a host is any device with an IP address that is not a router and that is attached to the network. WINS is a NetBIOS-over-TCP/IP mode of operation defined in RFC 1001/1002 as h-node or m-node; WINS clients default to h-node.

The first character, until recently, had to be an alpha character. DNS vs NetBIOS Since the inception and use of computers, there have been many names that have been given to these machines that have come to greatly make work easier on the general population. The hierarchical system, used by DNS, is a more flexible system that still guarantees a unique name. However, before you consider decommissioning WINS servers, identify any computers or applications that rely on NetBIOS, and determine the impact of removing NetBIOS name support from the network.

Read how to maintain and repair any desktop and laptop computer. If a name is not l5 characters long, it is padded with spaces (in binary format, with 0s) so that all names are always l5 characters plus the sixteenth function character. NetBIOS names must be resolved via an LMHOSTS file or via a NetBIOS name server, which in Windows is implemented as Windows Internet Naming System or WINS. Privacy Policy Clearly, this becomes a constraint very quickly, especially because all companies cannot possibly check with one another before naming a computer and bringing it online.

It was first designed at the University of California Irvine in 1983. It is often a shorter version of the FQDN.

A server named might have an alias of, for example.You'll learn more about this later in this chapter, and we'll discuss how and why aliases are used.

In Microsoft implementations of NetBIOS, the sixteenth character is a NetBIOS suffix. NetBIOS, an abbreviation for Network Basic Input/Output System, is a networking industry standard. (As NetBIOS can run on top of several …

The DNS Domain Name System is what translates your favorite domain names into IP addresses. However, if another host is named rosie, it cannot also be called rosiel.

*Tek-Tips's functionality depends on members receiving e-mail.

DNS vs NetBIOS Since the inception and use of computers, there have been many names that have been given to these machines that have come to greatly make work easier on the general population.

By joining you are opting in to receive e-mail. AD and DNS have pretty much done away with the need for NetBIOS and WINS, but if you do enable it, your ability to browse the other systems on your LAN is faster. That limitation has been removed and names can now begin with an alpha or numeric character. ■ Alias An alias is a any name used in place of another name. Shop |

| On a Windows XP/2000/Server 2003 computer, you can find your computer's name by right-clicking on My Computer and selecting Properties. Although RFC1001 defines 16 characters for a NetBIOS name, Microsoft uses the sixteenth character as a NetBIOS suffix to define various functions, as you'll see in a moment. (Alternately, you can select System from Control Panel to access the System Properties dialog box.) Aside from some software engineering changes that make WINS less vulnerable to malicious attack, WINS functionality has not changed from that available in Windows Server 2003. There are many links to online videos that explain how you can build, maintain, speed up, clean, and repair your computer yourself.
An organization can choose to create a private domain namespace and it does not have to be unique as long as it does not interact with public networks such as the Internet. Registration on or use of this site constitutes acceptance of our Privacy Policy. Remember that Microsoft NetBIOS names are limited to 15 characters even though RFC 1001 allows for 16.
