Network security is not working as expected. The Base Filtering Engine (BFE) service has either been stopped, or is not responding. BFE is a service that manages firewall and IPsec policies, and implements user mode filtering.  Disabling the BFE service reduces system security, and IPsec management and firewall applications might not work as expected.
