Enabling/Disabling Windows Firewall (Windows XP only)
Firewalls help protect your computers against hackers but an improperly
configured or malfunctioning firewall can prevent your computer
from connecting to the network. Presence of a firewall on
residential computers prevents the Clean Access server and the clean
Access client from communicating with each
other resulting in the following error.
Clean Access Server is not available on the network
(Important Note: This error can also be caused
if you are physically not connected to the network. Please check
and make sure you have a good connection to the network before uninstalling
firewalls.)
