Title: Disabling NetBIOS over TCP/IP - cannot browse network 7.6

Question: What's the deal with this? We have a TCP/IP network. DNS Servers. We used to have WINS servers, but I removed them. My client is Windows XP Professional.

If I Disable NetBIOS over TCP/IP on the WINS tab, I can no longer browse the network. I thought this would work through DNS. Can someone explain please? Quickly Reference Your Favorite Zones

This is a Windows 2000 domain network. We have AD integrated DNS, on 2 servers. All clients computers register with them. The zone is setup to not look Wins.

There are no errors in my event log, or the DNS event logs on both of the DNS servers.

I can resolve names fine. What I can't do is browse, meaning, if I open My Network Places, Entire Network, Network, DomainName, nothing shows up. If I enable the NetBIOS, the window populates.

Now shouldn't I be able to do that with NetBIOS disabled?

Yes, it should work...try removing and re-adding tcp/ip service.

If that doesn't do it try this: http://support.microsoft.com/kb/811259 or a pre-made tool: http://www.spychecker.com/program/winsockxpfix.html

If that does not work...then I am stumped.

How To Configure TCP/IP Networking While NetBIOS Is Disabled in Windows 2000 Server Article ID : 299977 Last Review : July 1, 2004 Revision : 2.1 This article was previously published under Q299977 IN THIS TASK Rank: Sage • SUMMARY• Installation

• Troubleshooting• Computers Running Windows 2000 • Computers Operating as WINS Clients • Down-Level Clients, Services and Programs

SUMMARY This step-by-step article describes how to configure a Windows 2000 server with TCP/IP networking while NetBIOS is disabled.

Windows 2000 provides for the ability to disable NetBIOS over TCP/IP (NetBT) for selected clients on an "as needed" basis. If you would prefer to only use DNS to provide name registration and resolution on a specified computer that is used in a specialized or secured role for your network, you can select to disable NetBT services for one or all of the network adapters that are installed on that computer.

back to the top Installation To disable WINS/NetBT name resolution: 1. Click , point to Settings, and then click Network and Dial-up Connections. 2. Click the local area connection that you want to be statically configured, and then click Properties on the File menu. 3. Click Internet Protocol(TCP/IP), click Properties, click Advanced, and then click the WINS tab. 4. Click Disable NetBIOS over TCP/IP. 5. Click OK, click OK, and then click OK. NOTE: Optionally, you can select the Use NetBIOS setting from the DHCP server if you are using a DHCP server that can selectively enable and disable NetBIOS configurations through DHCP option types. NetBIOS over TCP/IP can also be disabled for computers that are running Windows 2000 by using DHCP option types that are supported by the Windows 2000 DHCP Server service.

back to the top Troubleshooting Computers Running Windows 2000 • The computer no longer listens for traffic to the NetBIOS service at User Datagram Protocol (UDP) port 138, the NetBIOS name service at UDP port 137, or the NetBIOS session service at Transmission Control Protocol (TCP) port 139. • If the computer needs to participate in WINS as a client, it must be physically multihomed (that is, it must have other physical network connections active and available for its use) for it to continue communicating with and using a WINS server. back to the top Computers Operating as WINS Clients • The computer can no longer function as a WINS server to service WINS clients over the connection unless NetBT is re-enabled. • For those adapters to use WINS, you must either manually configure a list of WINS servers on the NetBT-enabled connections or provide such a list to these connections from a DHCP server.

NOTE: WINS servers that are configured in TCP/IP properties for the disabled network adapter do not

apply for other installed network adapters. back to the top Down-Level Clients, Services and Programs • NetBIOS defines a software interface and a naming convention, not a protocol. NetBIOS over TCP/IP provides the NetBIOS programming interface over the TCP/IP protocol, extending the reach of NetBIOS client and server programs to the WAN, and providing interoperability with various other operating systems. • The Workstation service, Server service, Browser, Messenger, and Logon services are all direct NetBT clients. They use TDI (Transport Driver Interface) to communicate with NetBT. Microsoft Windows NT and Windows 2000 also include a NetBIOS emulator. The emulator takes standard NetBIOS requests from NetBIOS programs and translates them to equivalent TDI primitives. • Windows 2000 uses NetBIOS over TCP/IP to communicate with prior versions of Windows NT and other clients, such as Microsoft Windows 95. Careful testing should be done before disabling NetBIOS over TCP/IP in any production environment. Programs and services that depend on NetBIOS no longer function after you disable NetBT services, so it is important that you verify that your clients and programs no longer need NetBIOS support before you disable it.

NOTE: Computers that are running an prior to Windows 2000 will be unable to browse, locate, or create file and share connections to a Windows 2000 computer with NetBIOS disabled. back to the top

Browsing network neighborhood is still a NetBIOS function. Always has been, probably always will be. WINS dependency has been replaced by Dynamic DNS. Windows XP only chages the order of name resolution to prefer DNS over WINS. You don't need WINS, but you do still need NetBios as long as you want to use Network Neighborhood functions. Everything else will work without NetBIOS enabled.
