Teefer driver is a software component placed between the operating system and network interface card drivers. Teefer driver is responsible for capturing all network traffic entering or leaving a particular interface so that the packets may be passed to the personal firewall and IPS component of the SEP client for analysis.

  2. Stop running Symantec services by opening START -> RUN and type smc –stop and click OK button. You may be asked for password (the same as for SEP uninstallation).
  3. Install Symantec Service Network Component by entering START -> Control Panel -> Network Connections and right-click Local Area Connection interface and select Properties. Then click Install button, select Service and click Add button. Select Network Service dialog appears – in the left pane select Symantec as Manufacturer and in right pane select Symantec Endpoint Protection Firewall and click OK. Installation of teefer driver is started (in case you are connected using RDP, connection may drop for few seconds). This will take approximately 20 seconds, no installation dialog is displayed.

  4. Start running Symantec services by opening START -> RUN and type smc –start and click OK. Open Symantec Endpoint Protection interface to verify successful install of teefer drivers.
