A. Normally, you can easily disable NetBIOS over TCP/IP using the WINS tab of your IPv4 network configuration. On Server Core, however, you don't have access to the Networking Control Panel Applet. You can still disable NetBIOS over TCP/IP through the registry:

  1. Start the registry editor (regedit.exe).
  2. Move to HKLM\SYSTEM\CurrentControlSet\services\NetBT\Parameters\Interfaces.
  3. Select each interface GUID.
  4. Any GUID that has a NetbiosOptions value that is 0 (Use NetBIOS setting from the DHCP server) or 1 (Enable NetBIOS over TCP/IP), set to 2 and click OK.
  5. Close the registry editor.
