This article describes NetBIOS Browsing Console (Browcon.exe), a utility that you can use to troubleshoot NetBIOS network browsing problems. NetBIOS Browsing Console builds on the power of Browstat.exe, a command-line tool that is included in Windows 2000 Support Tools.
Browstat.exeNetBIOS browsing is used in many programs and utilities that are designed to run on Windows-based networks. Programs that allow users to browse the network for computers or printers typically use NetBIOS browsing. When individual computers or groups of computers are missing in the list, network administrators must try to determine why.
Browstat.exe is an extremely powerful command-line tool that can help you determine the root cause of a browsing issue and then help to fix it. However, to use Browstat.exe effectively, you must be an experienced troubleshooter who has a detailed knowledge of how NetBIOS browsing works. In routed IP environments, you may have to run Browstat.exe on several systems that are located in different locations on the network and coordinate the data that is returned from each test. Because of these complexities, few troubleshooters take advantage of Browstat.exe. For additional information and step-by-step instructions about how to use Browstat.exe, click the following article number to view the article in the Microsoft Knowledge Base:
188305Instructions for using Browstate.exe are also described in the "MS Windows NT Browser" white paper. This white paper also includes detailed information about the browser services that are available in Microsoft operating systems. To view this white paper, visit the following Microsoft Web site:

NetBIOS Browsing ConsoleNetBIOS Browsing Console leverages the power of Browstat.exe and makes Browstate.exe easier to use and understand. NetBIOS Browsing Console is a Windows program that was built on Microsoft .NET Framework (v1.1.4322). Like Browstat.exe, it runs on Microsoft Windows NT 4.0 and Windows 2000 and later operating systems that have the TCP/IP protocol installed. After you install and start the console, you enter relevant information in the console that helps to automate many troubleshooting steps.
This information that you enter includes the following:
The NetBIOS Browsing Console AgentThe NetBIOS Browsing Console uses an agent (the NetBIOS Browsing Console Agent) to gather and report NetBIOS browsing data from remote networks. The agent must be installed on a single system on each logical subnet on the network. The system’s name is entered in the “network profile” on the NetBIOS Browsing Console, so that it can be contacted during troubleshooting. The agent is a small console application that does not require any configuration. Just double-click its icon to start the agent. By default, the agent listens on TCP port 49911 for console connections. It displays the connection details each time a console connection is tried. Version 2.0 of the agent (Nbcagent.exe) does not require the Microsoft .Net Framework. Just copy it and Browstat.exe to any directory on a system, and then run Nbcagent.exe. The combined size of the agent and Browstat.exe is less than 200 KB, and neither file requires any registry entries. The NetBIOS Browsing Console Agent (version 2.0) has two optional switches:
Use NetBIOS Browsing Console to troubleshoot your NetBIOS browsing infrastructureAfter you deploy the console and agents, you can quickly collect data that is used to troubleshoot typical NetBIOS browsing issues. This makes it easier and faster to diagnose and correct problems with your NetBIOS browsing infrastructure.
The left pane of NetBIOS Browsing Console is populated with browsing data that is collected from the subnets that are used during the troubleshooting process. This information includes the domain master browser, all the subnet master browsers, and subnet backup master browsers that are registered with the domain master browser. The list also includes the subnet master browsers that are involved in the problem and the browse lists that are retrieved directly from them. This information can help you determine the systems that are registered with a particular browser and the systems that are not. Some system attributes are included in this list, such as the operating systems that the systems are running and their browser roles.
NetBIOS Browsing Console can help you to troubleshoot when a single system or a group of systems is missing from a client’s browse list. To start troubleshooting, type the name of the missing system, the Windows domain that it is a member of, the logical IP subnet that it is located on, and the subnet that the client is on, and then click Start Troubleshooting. The console finds and catalogs the domain master browser and the various subnet master browsers that are involved in the problem. The console connects to and queries agents as necessary. It reports connectivity problems if any are encountered during the troubleshooting process.
The network profile is updated with the new information each time you click Start Troubleshooting. This information can help you to pinpoint the browse lists that contain the missing systems and the browse lists that do not contain the missing systems. If the console finds any problems, it reports them in the right pane of the main form. If it determines any possible causes of the problems, it displays reports in HTML format in the default Web browser.
