How good is Window's Firewall in comparison to Norton Personal Firewall or other commercial firewalls?
If Window's Firewall is, in fact, not as good as some other commercial firewall, is the difference significant enough to warrant buying a different firewall?  If so, which ones are good?

Thanks in advance for the response.

Greetings, wdwcuwa !

Windows Firewall blocks only incoming traffic. Norton personal firewall and other commercial firewall blocks outgoing traffic as well as incoming.

Kerio is a good firewall, takes up little resources, and has a free version

The free Zone Alarm is way better than Windows Firewall which blocks both traffic.

Windows Firewall only blocks or patrols incoming traffic and it can be easily turned off by another application, worm etc.

Agree with both however is you are planning to move to Vista I believe the Windows Firewall blocks both incoming and outgoing.

There is one plus to the windows firewall.  It secures the OS at boot time, where zone alarm cannot.  For 3rd party firewalls, the OS must start then the OS will run the 3rd party firewall as an additional service(typically).  The windows firewall is built into the OS, so it is active as the OS starts.

wdwcuwa,

The main difference between Windows XP Firewall, and other software from third party, is that windows firewall only blocks incoming traffic, you can't control outgoing traffic, but in Windows Vista, you can control both incoming and outgoing traffic.

Thank you all for the helpful and insightful responses. However, I have one follow up question.  What is the main difference between "incoming" and "outgoing" traffic?  Is it that incoming traffic is people trying to attack and infect my computer, while outgoing traffic is my infected computer trying to communicate with / infect other computers?  
Thanks again.
