NetBIOS is an non-routing protocol(unlike RIP OSPF asf). It is unroutable (just useable on local LANs via Hubs or Switches.
when is NetBIOS routable
No, you cannot have the same netbios names because there would be a conflict between the computers and Netbios names are unique names.
No DNS is based on the hirearchal system not NetBIOS.
Lmhosts: provides NetBIOS-name-to-IP-address resolution
The command to clear the NetBIOS name cache table is nbtstat -R. This command releases and refreshes the NetBIOS name cache, effectively clearing it. You can run this command in the Command Prompt on a Windows system. Additionally, you can use nbtstat -S to view the current NetBIOS name cache entries.
you see the file name is WINS. which stands for window internet name service see the resolution happens like this (p.s WINS, is not a file name it is a protocol) NetBIOS, broadcasts names to listening nodes on the network. NetBIOS utilizes a User Datagram Protocol UDP, query to broadcast names. NetBIOS names identified computer on the network before the introduction of Windows 2000. The NetBIOS name is resolved to an IP address through windows Internet Name Service WINS,broadcasting, or the LMHOSTS file. If the LAN is a NetBIOS LAN, the NetBIOS name is then the network address. The NetBIOS name is assigned by an administrator when the operating system is installed. To enable communication, the following requirements exist. i hope i have helped
The nbtstat utility is a command-line tool in Windows that is used to troubleshoot NetBIOS over TCP/IP (NetBT) issues. It displays protocol statistics, current NetBIOS connections, and the NetBIOS name table for local and remote machines. This tool can help identify problems related to name resolution and can clear the NetBIOS name cache. Additionally, it can be used to refresh the NetBIOS name table, facilitating better network communication.
Yes, there are several NetBIOS commands that can be used for network services on Windows systems. Common commands include nbtstat for displaying NetBIOS over TCP/IP statistics, net view to list shared resources on a network, and net use for connecting to shared resources. These commands can help in managing and troubleshooting network connections involving NetBIOS.
Worth noting is the popular confusion between the names NetBIOS and NetBEUI. NetBEUI originated strictly as the moniker for IBM's enhanced 1985 NetBIOS emulator for token ring. The name NetBEUI should have died there, considering that at the time, the NetBIOS implementations by other companies were known simply as NetBIOS regardless of whether they incorporated the API extensions found in that emulator. For MS-NET, however, Microsoft elected to name its implementation of the NBF protocol "NetBEUI" - literally naming its implementation of the transport protocol after IBM's second version of the API. Consequently, even today, Microsoft file and printer sharing over Ethernet continues to be called NetBEUI, with the name NetBIOS commonly used only in reference to file and printer sharing overTCP/IP. In truth, the former is NetBIOS over NBF, and the latter is NetBIOS over NBT.
If you have Windows ME/9x and below systems, use WINS for a NETBIOS name resolution server as DNS does not resolve up NETBIOS.
The best method of preventing NetBIOS attacks is to disable NetBIOS over TCP/IP on devices that do not require it, thereby reducing exposure. Additionally, implementing a robust firewall to block unsolicited NetBIOS traffic and using strong authentication methods can enhance security. Regularly updating systems and applying security patches can also mitigate vulnerabilities associated with NetBIOS. Lastly, educating users about the risks and implementing network segmentation can further protect against potential attacks.
