In your last vulnerability scan you might find the following “Windows NetBIOS / SMB Remote Host Information Disclosure”. This finding is normally due to the reason that NetBIOS is still enabled on the system.
So the solution here is to disable NetBIOS on a Windows OS via the following:
1.) From the Network and Dial-up Connections icon in Control Panel , select Local Area Connection and right-click Properties .
2.) On the General tab, click Internet Protocol (TCP/IP) in the list of components, and click the Properties button.
3.) Click the Advanced button.
4.) Click the WINS tab. Click Disable NetBIOS over TCP/IP.
Legacy Windows systems like Windows 9x or Windows NT relay on NetBios. So perform a deep check before you disable this feature.
