Dont need inbound protection as im already behind a NAT. All i need is outbound protection that doesnt chew up heaps of resources unlike the full blown ZoneAlarm and similar highend software firewalls. Will windows firewall be enough for this? What do companies use to protect their client pcs?

If you are running behind a NAT then your need for a firewall is lower. However, the NAT will not report if there is an intruder trying to get to your machine. I wouldn't think you would need ZoneAlarm, or even the windows firewall, however if you move the PC to a new location, or plug it into a jack that isn't behind the network address translation you will need that protection software. You can just disable the software, or turn the level of security down on it. If your company requires the software running on the PC then you have a different situation. You will need to run it as well as being behind the NAT.

The free version of zonealarm should be fine if you want a software firewall- it's less resource hungry than mcafee or norton's software firewalls.
The Windows XP firewall does almost nothing with respect to outbound traffic.
Most companies have dedicated hardware firewalls (often these devices are also providing NAT) Those duties are generally handled further upstream than the desktop. Cisco and Sonicwall are two widely deployed brands. See the link below for Global Technology Associates.

windows firewall is not even really a firewall and it is good for nothing. might as well not even turn it on due to the fact with it on your getting the same protection as if it were off. you need a firewall. you also possibley need more ram. i hear everyone complaining this eats up so many resources or that does. i have no issues with anything i use. i currently have 26 processes and i am using norton internet securities 2007 and my cpu is between 4 and 5 percent.

You are talking about completey different things.
Most companies have there own servers that are set up as Virtual Private Networks many require CDS username and Passwords to even get on the computer at all.
Most all Routers are behind there firewall as well as Windows firewall not to mention your Internet Service Provider is behind a firewall.
So when is enough enough, Never, To many goofballs out there I don't think you can be to safe.
I will suffer the loss of some speed, not to have to worry about always having to re format and using the System Restore feature.
My opinion is there is alterior motives behind this sillyness to keep us paying, Loard we wouldn't want them to fix things once and for all.
