2. Turn off NetBIOS via Command Prompt
- Alternatively, users can disable NetBIOS with the Command Prompt. First, open the WinX menu.

- Note the index number of the adapter you need to disable NetBIOS for and include that in the wmic nicconfig where index command. For example, to disable the NetBIOS for the network adapter listed as three, users would enter the following command: wmic nicconfig where index=3 call SetTcpipNetbios 2.
- In the above command, three is the index number for the adapter and two disables NetBIOS over TCP/IP. Press the Enter key after entering the command to disable NetBIOS.
3. Edit the Registry
- Users can also disable NetBIOS for more specific network adapters by editing the registry. Open the Run accessory.
- Enter regedit in Run and click OK, which will open the Registry Editor.
- Open this registry path in the Registry Editor:
- Select a Tcpip registry key for a network adapter.
- Double-click NetbiosOptions to open the window shown directly below.
- Erase 0 and enter 2 in the Value data box.
- Press the OK button.
