To disable NetBIOS, you will need to go into your network interface adapter settings under Control Panel in Windows.

Look for the ‘Network Connections‘ in Windows XP. For Vista/Windows 7, it is located in a different folder ‘Network and Sharing Center‘.

– Right-click on an LAN adapter and select “Properties”

Once you are in the “Properties” page, highlight the “Internet Protocol(TCP/IP)” option and click the “Properties” button.

– Click the “Advanced…” button
– Click on the ‘WINS‘ tab
– Choose the ‘Disable NetBIOS over TCP/IP‘

Click ‘OK‘ twice and then ‘Close‘

This will disable Netbios on this interface.
