Firewall blocks Internet access need help

I have no idea where is the best place to report this, but I am having great difficulties with the firewall; the only way that I can browse the web is by disabling it and using the Windows XP firewall. I have SP3 all updates, and I am hopping mad. A solution will mollify me somewhat.

Throughout the day I have been spending precious time restoring images, checking hardware and so on. The firewall was the last thing I thought would have been wrong. Grr.
