bently, I am sure you will get all kinds of answers to your question. Like you I have had no problem running XP firewall and ZoneAlarm Free at the same time using XP SP-1. No experience with SP-2 yet. My opinion would be to use whatever works without problems; however, I serriously doubt running two firewalls will add additional security. I prefer ZoneAlarm because it checks outgoing as well as incoming.
Best of luck!
I ran MS firewall and Kerio at same time since I installed XP home. I have never noticed any conflicts.
I installed SP2 a few days ago and now have the updated MS firewall installed with Kerio Personal firewall.
I have read conflicting reports on running both.
So should I run both, or should I disable the MS new firewall?
