The Base Filtering Engine (BFE) is a service that manages firewall and Internet Protocol security (IPsec) policies and implements user mode filtering. Stopping or disabling the BFE service will significantly reduce the security of the system. It will also result in unpredictable behavior in IPsec management and firewall applications.

The Base Filtering Engine service runs as NT AUTHORITY\LocalService in a shared process. It shares an executable file with other services. If the Base Filtering Engine fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the BFE service has failed to start.
Base Filtering Engine will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.
If the Base Filtering Engine is stopped, the following services will not start and initialize:
