I just installed Total Protection 2009 and learning how to use the network manager. I look at the layout, and there's one machine listed with no computer name, but just an ip address of 192.168.0.103. both that computer and my computer is connected to the router accoriding to the diagram, but I can't get any information on the 192.168.0.103.
yes, i do use a wireless router, but the thing is, if mcafee picks up other machines connected, shouldn't I at least see the name fo the computer id like how it does with mine? Why does it only show only an ip address? that doesn't tell me anything. I can't tell how to translate that.
Can you explain?
Also, I didn't see the option to set something unknown as an intruder. It only lets me have the option to hide it from view
To be honest I have no idea. There is a help section in the Security Center to aid you. I connect by wire to my router and the other person who connects wirelessly here is not trusted on my machine and is markied as an intruder also, they still can coinnect. Unless you are using your wireless router to connect with other machines in the same location I don't think you need to trust the network at all.
Public - random data, connections, who-knows-who's-out there? Private - Only devices I know and trust are directly to the same hardware.
When you choose "Do not trust this network" you are basically setting the firewall to a default deny policy. It should not disconnect you from the internet or your wireless access point. Otherwise, your 'local' networks have a default allow policy since it's a "trusted" network. The firewall can still be told to block/allow traffic as needed.
The basic system only sees IP addresses. The "name" is an added feature where the client machines send a "host name" during the DHCP (Automatic IP config).
You should try doing an IPCONFIG /RENEW on the trouble system.
There are other ways this information could be discovered. The 2 other most common ways is through NETBIOS/SMB (Windows File/Printer Sharing) and the other is through a special protocol driver called LLTD (link-layer topology driver).
With NETBIOS/SMB it's possible those features or network ports are disabled or blocked, thus disabling that method.
The LLTD is a feature of Windows Vista and only works if your network is NOT set to public and/or you allow "Network Discovery". There is a driver download from Microsoft that will allow the drivers to install on Windows XP as well.
It is safe to remove older networks that you are no longer connected to. You should not be able to remove the network you are currently connected to.
If you leave it as trusted, it is possible for other machines on the same network (wireless or wired into the same router) to see your computer and potentially access insecure services.
Services are programs providing a feature through the network. Examples are web servers and Microsoft File and Printer Sharing. These can be password protected. Security depends on the service not being exploitable to leak information or allow unauthorized access.
