Does your computer have a unique firewall the others don’t?

It does. My firewall is part of Norton Internet Security 2009. I still had the same access problems, however, when I uninstalled NIS.

Hmmm...Well, this isn’t a thrill, but maybe a reinstall might be the ticket.
Maybe geeks can provide a better answer than this.
