NetBios

Hi

I have two computers connected to the same router/modem.

However, these machines are not networked. I keep getting inbound requests from the other machine into my main machine.

Does anyone know how I can totally block these requests, and set my machine so it has as little access by other machine as possible. I won't be using this machine to network, ever.

Howver I do use programs such as Utorrent, so I still need functionality there.

I have turned off sharing and homegroups. I am not sure what else to do.

Also does NetBios affect my security, and if so, how can I safely disable it without losing required functions?

Cheers

A service TCP/IP NetBIOS Helper is what you would turn off. You can also set some options in the windows firewall that block local communications.

As well as turning the NetBIOS service off in the control panel, you need to turn it off at the connection also. You shouldn't need to configure the Windows Firewall at all.

 

If you disable the service, doesn't it kill it all-together? I haven't specifically tried, but I was assuming that the NIC properties you refer to would be to turn it off per adapter but not entirely stop the service. Be interesting to know the heirarchy of this.

As I've noticed in the past, unfortunately, no. I believe you might be able to just disable it in the network options and leave the service, but I always disable both, since leaving the service running seems pointless. If I disable only the service I still see NetBIOS packets. But you can pretty much kill it by disabling the service and the network option.

 

Thanks FD. A very simple and straight forward explanation..

this should be a sticky,great information about security.

 

Don't forget that if you want to isolate one computer from the rest, you can use the firewall. In this manner specific computers can still communicate, but block others. This might allow you to have 2 childrens computers that communicate between each other for games etc, while having 2 adults computers that also communicate, share printing/files etc, all the while they can be on the same subnet to access the router and still be segregated from netbios.
