At the present time, your network is spread across four geographic regions throughout North America. The company has five offices in the United States, and ten offices throughout Canada. Each office has a least four populated segments, with the maximum number of segments at the corporate office having 20 populated segments.

You are the network administrator on a multisegment network. At the present time, your network is spread across four geographic regions throughout North America. The company has five offices in the United States, and ten offices throughout Canada. Each office has a least four populated segments, with the maximum number of segments at the corporate office having 20 populated segments.

The only LAN protocol in use is TCP/IP at all facilities. The network infrastructure includes Windows 2000 routers separating the internal segments, and 100 Mbps switches to manage network traffic within each segment. The network services infrastructure includes Windows 2000 DNS, Windows 2000 WINS and Windows 2000 DHCP Servers all participating in a single Windows 2000 Active Directory Domain.

The network was recently upgraded from a Windows NT 4.0 Domain and the network clients had been mixture of Windows 95, Windows 98 and Windows NT 4.0 Workstation. After the network upgrade was complete, all servers were running Windows 2000 Advanced Server and all workstations were running Windows 2000 Professional.

About a week after the completion of the upgrade, you receive a call from several of the sites complaining that one of the servers on segment 192.168.44.0 does not show up in the browse list. Since this is one of the main SMB file servers for the region, you call up the other offices and they report that the same server does not show up their Browse Lists. You check the network that is local to the server, and again, it does not show up on the browse list of any of the network segment.

You ping the server by NetBIOS name, DNS host name and by IP address and the ping is successful on all counts. You attempt to connect to a well-known share on the server via its UNC path and you again are successful. You confirm that all Domain Controllers on the network are functioning correctly, and you run the Browmon and Browstat programs from the Windows 2000 Resource kit to confirm that the Browser Service is functioning correctly on the network.

Why is the server not appearing on the Browse List?

  1. A firewall or packet filtering router has blocked outgoing broadcast messages on UDP Port 138 between the segment Master Browser and the WINS Server.
  2. NetBIOS over TCP/IP has been disabled on the missing Server
  3. The WINS Server has a static mapping for the missing Server which points to an incorrect IP address
  4. The DHCP Servers have been incorrectly configured and have made all network clients NetBIOS m-node clients
  5. The missing Server has been configured with configured with an incorrect address for its WINS Server.
