    I was wondering if you are behind a Nat Router instead of a Software firewall is it safe to do the following and disable Netbios over TCP/IP, if you are not sharing any files or printers on a network and can this cause any security problems?

    1. Click Start, point to Settings, and then click Network and Dial-up Connection.
    2. Right-click Local Area Connection, and then click Properties.
    3. Click Internet Protocol (TCP/IP), and then click Properties.
    4. Click Advanced.
    5. Click the WINS tab, and then click Disable NetBIOS over TCP/IP.
    You can also disable NetBIOS over TCP/IP by using a DHCP server with Microsoft vendor-specific option code 1, ("Disable NetBIOS over TCP/IP"). Setting this option to a value of 2 disables NBT. For more information about using this method, refer to the DHCP Server Help file in Windows.

    cheers for any advice,

    Avec

    Short answer. It should not cause any security problems that I am aware of.

    Thanks,

    Sure, you can disable netbios in that manner, and as long as everything works ok, then you've got no problems. In fact, it might be considered wise to do so..

    If you are not using it, no harm in disabling it. When behind a router, those services are not exposed to the Internet (unless for some reason you have forwarded those ports).

    6. Go into services, stop and then set manual or disable TCP/IP NetBIOS Helper service.

    Yes it is safe to do so, and as mentioned even wise to do so. If you are using a network try using NetBEUI or IPX/SPX instead of TCP/IP. They are much safer, but as mentioned if you are behind a router they are not exposed to the internet anyway.
