I wouldn't say that it's *always* unecessary, just not in a typical home
envirnoment. If I were using my home PC to do "real work" that mattered if
it were lost then sure, my level of paranoia would escalate and I would
consider a software firewall. Like I said, my work laptop has it. I try
to restrict internet access for the kids and have a nightly backup to make
sure that we don't loose the family photos and our e-mail in the event of a
hard drive crash.
While I might be upset if covert software such as Sony's rootkit got
installed without my knowledge it's not worth it to me for my home
especially if I have to buy it for 8 computers. (Remember--the subject is
"Home network problem".)

While I don't agree that a software firewall is unnecessary, I do agree
with Dave's summary. Don't just de-activate, but uninstall ZA. Get the
share working. Then re-install ZA. If the share breaks, you have an
obvious path to troubleshoot (or seek support from the vendor).
As has been mentioned before, many of the better approaches to security
involve a layered approach. Layer the software firewall on top of the
hardware firewall. Layer the AV & AntiSpyware apps ontop of that.
The software firewall specifically provides a layer of support that the
hardware firewall doesn't. For instance, the hardware firewall would
not stop the privacy invasion caused by the Sony rootkit exploit.

That sounds like an internal security problem. If you have a virus or
spyware that's harvesting your personal info then deal with that with
anti-virus or anti-spyware software. Catch it before you get infected.
If you are logging on to a commercial web site and entering things like
credit card numbers then make sure that it's a secure connection. If
not then don't blame them for sniffing out your data. If your kid set
up the network/Internet connection for you and you are using it without
knowing you've got a secure environment, again, that was your decision.
Personally, I've got anti-virus and anti-spyware software and I'm
trusting my router to keep hackers out. It may not be perfect but I
also don't triple-lock my doors, have bars on my windows, or let my kids
secure the Internet for me either. If it were a business environment I
would be more concerned about security. At home I'm more concerned with
restricting what web sites my kids can go to. I can also see the other
PC's on my network.
Regardless of your desired level of security I still advocate taking
Zone Alarm out of the mix until sharing works as expected. It may not
be part of the problem but you may not know that. Once you have things
working you can put it back in if that's what you want.

I have a similar situation at home, using a consumer-level
router-firewall, and ZA.
Unfortunately for Jeff, my 16-year old got the "network" set up, and we
had some issues, but he figured them out. I probably should have him
give me a rundown of what he did. But, I digress.
The basis for deciding to do this was that esteemed members of this list
educated me (let's see how accurately I remember the lesson!) that the
router-firewall only restricts things coming in, and doesn't care if
you're sending all your keystrokes, bank account numbers, social
security numbers to some friendly guy in Russia. That's where the
ZA-type firewalls come into play.
Did I remember the lesson correctly?
