    NetBIOS over Tcp/IP - Do I want this enabled?


    On previous versions of Windows, I've always disabled NetBIOS over Tcp/IP.
    Are we still doing that?

    I'm on a stand alone computer, with all Sharing disabled. No network, no printers.
    As far as I know I have no programs that require it. What is the current thinking on this?

    It's not something that I have ever disabled. But I have been on a home lan since around 1998.

    I was kind of looking for a bit more.

    I don't see why you need to disable the service it doesn't cause any problems.

    Sorry, I guess I just didn't see the point in disabling it.

    With a backup ready,try it and see.There are far too many dependencies in computers to be conclusive without practical experience.
    Be interested to hear the outcome.

    I always have recent full OS image backups.

    From what I've read... if whatever DNS server I'm on goes down, NetBIOS tcp/ip takes over. Other than that (in my case only), there's no need for it.

    Hackers (port scans) and unsolicited traffic. Virtually every PC today is on a shared network (no public IP).

    WannaCry uses the MS17-010 exploit to spread to other machines through NetBIOS.

    Found a handy article that shows how to check NetBIOS status, and how to disable it completely, if desired: Testing and Disabling NetBIOS - 1. Frontline.
    FWIW, I've never messed with it on my Windows PCs, and it's never caused me any problems.
    Here's a link to the NetBIOS chapter from TCP/IP Unleashed, back from 2001/2002: NetBIOS and TCP/IP | NetBIOS and TCP/IP | InformIT.
