System Question

How do I get rid of the pop up system that access port nbname (137)? When I read the forum here, somebody suggested to create a trust zone, how do I do that? Please help.

You can set up a trusted zone by going to firewall/common tasks/stealth port wizard and select “define a new trusted network” and selecting or defining your nrtwork there. Or you can go to advanced/network security policy and add an explicit rule under "system to block and not log them if you don’t want to allow them- block/udp/in/any/any/any/137. Depends on whether you want to trust all the computers on your LAN or not.

“define a new trusted network” and selecting or defining your nrtwork there.
Then I click “NEXT”. Click "I would like to trust an existing ‘My Network Zone’. That’s it? Will I be exposed to outbound attacks?
