I have a McAfee Fire wall on my computer, do I need a privacy wall also? If, yes why?

Hi... pls help me or give me some suggestion :)
I have 2 firewalls in my office, Firewall A and Firewall B
Firewall A (the one connect to Internet):
trust ip: 192.168.1.1/24 (static IP)
untrust ip: DHCP (ISP assigned)
NAT is on at both trust and untrust interfaces.
DNS set.
Firewall B (connect to my NIC):
trust ip: 192.168.11.1/24 (static IP)
untrust ip: 192.168.1.34/24 (static IP)
my pc ip: 192.168.11.2 (static IP)
The picture is:
Internet --- Router --- Firewall A --- Server --- Firewall B --- my pc
When I try to login into my PC, it said, Domain server was unable to validate my password. I have been told if i set the IP as static in my PC, just ignore that error message.
Do you have any idea what went wrong?
Thank you very much....

Goto control panel- administrative tools - services.
Scroll down until u find Windows Firewall/ Internet Connection Sharing, double click, and set the start-up type to: automatic

What happens when you try to turn on the firewall?
The firewall will not stop all types of popups. You need to make sure that popup blocking is enabled in yoru browser, and make sure to run up to date anti-virus and anti-spyware tools regularly.

I'm using Zonealarm & i'd tell you that its blocking my program including "download accelerator" "Yahoo Messenger" "Opera" etc... Whats next?? "Explorer.exe" Thank god i've read the manual otherhand, none of my program would work cause Zonealarm would be blocking all my applications.

You note that the downside of a hardware firewall is that it only blocks incoming, not outgoing traffic. Then for a software firewall, you recommend the built-in Windows XP firewall. However, unless things have changed since I last looked into it, doesn't the XP firewall block only incoming as well and let all outgoing go, no matter what?
