A Windows machine will lose connectivity for a brief period of time during the network
driver installation while the agent installs a network driver to examine traffic.
This only happens the first time a policy is applied that includes one of the following:
- Web Reputation
- Firewall
- Intrusion Prevention
A Windows machine uses the same driver is used for all three protection modules listed
above. Turning on web reputation, firewall or intrusion prevention after one of those
features already turned on will not cause another network blip. You may see a similar
interruption in network connectivity when the agent is upgraded (as the driver may
also need to be upgraded).
