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.
