His answer "Use them both" pertaining to two firewalls with WinXP SP2 is in conflict with Microsoft. I have sent a question 'reply' to him which has not been published or acknowledged. Have also sent the following email to Mr. Vamosi on September 19, 2004 and have received no answer:

"Dear Mr. Vamosi,
This is in regards to your article, "Which Firewall to Lose"
http://reviews.cnet.com/4520-10166_7-5507759-1.html?tag=cnetfd.ld
I am a member of the CNet Community Forums and in the Viruses and Security
Form when I posted that Microsoft says only use one firewall, a Moderator
called my attention to your article indicting a conflict.

In the Microsoft Help and Support Center for SP2:
"Off: This setting turns Windows Firewall off. When you choose this
setting, your computer is much more vulnerable to harm from unknown
intruders or viruses from the Internet. This setting should only be used by
advanced users for computer administration purposes, or if your computer is
protected by another firewall."
"In Microsoft Windows XP Service Pack 2 (SP2), Windows Firewall is turned on
by default. (However, some computer manufacturers and network administrators
might turn it off.) You do not have to use Windows Firewall-you can install
and run any firewall that you choose. Evaluate the features of other
firewalls and then decide which firewall best meets your needs. If you
choose to install and run another firewall, turn off Windows Firewall."

Under, "Tweak the Firewall" for SP2 one of his paragraphs echoes the MSKB
and the MS Help & Support Center:
"Once you've installed a bidirectional firewall, I recommend disabling the
Windows Firewall altogether. Occasionally, firewalls obstruct an application
you're trying to use over a network connection--and there's nothing more
frustrating than spending a half hour tweaking, disabling, and even
uninstalling a firewall, only to discover that the other firewall was the
culprit. To disable the Windows Firewall in the Security Center, click the
Windows Firewall link at the bottom of the dialog box, check Off (not
recommended) in the next window, and click OK."
So, did you mean to say "Use them both"...Zone Alarm Pro and Windows XP SP2
firewall?

Also Lee, in Microsofts "Frequently Asked Questions About Internet Firewalls" they state:
".....Using two firewalls on the same connection could cause issues with connectivity to the Internet or other unexpected behavior. One firewall, whether it is the Windows XP Internet Connection Firewall or a different software firewall, can provide substantial protection for your computer."
Could you please pass this on to your boss to pass to Mr. Vamosi or to Mr. Vamosi's boss.
