Testing and Disabling NetBIOS

How to Test and Disable NetBIOS on Windows Servers
Determine if NetBIOS is Enabled
  1. Log into your dedicated server using Remote Desktop
  2. Click on Start > Run > cmd.
  3. Enter:
    nbtstat -n
  4. If you get any response other than
    "Failed to access NetBT driver -- NetBT may not be loaded"
    this means NetBIOS is enabled.
  5. Run this script on the server to disable it completely:
    net stop "TCP/IP NetBIOS Helper"
    net stop netbt
    sc config netbt start= disabled
    sc config lmhosts start= disabled
  6. Confirm that it's been disabled by going to Start > Run > cmd > nbstat -n.
