The Windows Firewall is, to say the least,
pretty basic. However it is rather more configurable than the XP's original
Internet Connection Firewall. If you are unable to access a particular web site
it may be that the firewall is blocking incoming traffic from that site. In this
case you need to use the exceptions facility in Windows Firewall to correct the
problem.
