In case you do not want the network address to appear in your LAN settings list you can remove it from the list.
To do this:
1. Select Options
2. Select System
3. Press the Settings in the LAN Setting field.
4. You will see the LAN Settings dialog window
5. Highlight the desired Network Address
6. Click the Remove button to remove the network address
Actually removing the address from the list means the same as keeping the corresponding boxes under NetBIOS and Trusted columns empty (Limited Access to LAN level).
Warning: Removing network address from the list means NetBIOS communications will be disallowed for that address.
