when NetBIOS shuts down on a server running Windows Server 2003
This step-by-step article describes how to configure a computer running Windows Server 2003 with a TCP/IP network when NetBIOS shuts down.
running on a Windows Server 2003 computer, you can close the selected client NetBIOS (NetBT) on TCP /IP as needed. If you want to use only DNS to provide name registration and resolution on a specific computer that is used for specialized roles or security roles on your network, you can choose to turn off NetBT for one or all of the network adapters installed on that computer. service.
Configuration
To turn off WINS/NetBT name resolution, follow these steps:
- Click Start , point to Settings , and then click Network Connections .
- Right-click the local connection you want to statically configure, and then click Properties.
- Click Internet Protocol (TCP/IP), click Properties, click Advanced, and then click the WINS tab.
- Click to disable NetBIOS over TCP/IP.
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 program. For example, if you only communicate with computers that run products that use DNS in Windows Server 2003 (Microsoft Windows XP or Microsoft Windows 2000), computers whose names are registered with DNS, or if you use an application that recognizes DNS If the program communicates with an Internet computer, you can turn off WINS/NetBT name resolution. Do not turn off WINS/NetBT name resolution if the version of Windows on which the computer you are communicating with may use WINS or an earlier NetBT class application such as Microsoft Windows NT, Microsoft Windows Millennium Edition, Microsoft Windows 98, or Microsoft Windows 95. - Click OK, click OK, and then click OK again.
NOTE: If you use a DHCP server (which can have the DHCP option type selectively open and close the NetBIOS configuration), you can also choose to use NetBIOS setting from the Dynamic Host Configuration Protocol (DHCP) server settings. When you use the DHCP option type supported by the Windows Server 2003 DHCP Server service, you can turn off NetBIOS over TCP/IP for computers running Windows Server 2003.
Computers running Windows Server 2003 operating system
- The computer no longer listens for traffic on the following services: NetBIOS datagram service at User Datagram Protocol (UDP) port 138, located The NetBIOS Name Service for UDP port 137 and the NetBIOS Session Service for Transmission Control Protocol (TCP) port 139.
- If a computer needs to join WINS as a client, it must be physically multi-hosted (that is, there must be other active physical network connections available for it) so that it can continuously communicate with and use the WINS server. WINS server. Computer
as WINS client running - If you no longer open NetBT, the computer will not be able to act as a WINS server on connection to service WINS clients.
- For adapters that use WINS, you must manually configure a list of WINS servers in an open NetBT connection, or you must use a DHCP server to provide a list of WINS servers for those connections.
NOTE: TCP /IP properties for the WINS server off the network adapter configuration does not apply to other installed network adapter.
Level Clients, Services and Programs
- NetBIOS is a software interface definitions and naming conventions. It does not define a protocol. NetBIOS over TCP/IP provides a NetBIOS programming interface on the TCP/IP protocol. It extends NetBIOS client and server programs to wide area networks (WANs). It also provides interoperability with a variety of other operating systems.
- The workstation service, server service, browser service, messenger service, and network login service are all direct NetBT clients. They communicate with NetBT using the Transport Driver Interface (TDI). Microsoft Windows NT, Windows 2000, and Windows Server 2003 also include the NetBIOS emulator. The emulator obtains standard NetBIOS requests from NetBIOS programs and converts them into equivalent TDI primitives.
- Windows Server 2003 uses NetBIOS over TCP/IP to communicate with earlier versions of Windows NT and other clients such as Microsoft Windows 95. Before
closed NetBIOS over TCP /IP in any production environment, you must be carefully tested. NetBIOS-dependent programs and services will not work after you shut down the NetBT service, so it's important to ensure that your clients and programs no longer need NetBIOS support before shutting down the NetBT service.
NOTE: Run earlier than Windows 2000 operating system, the computer will not be able to browse, locate, or create a NetBIOS connection is closed in Windows Server 2003 computer running the product file and print sharing.
