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.

Base Filtering Engine logs on as NT AUTHORITY\LocalService and runs in a shared process of svchost.exe. If Base Filtering Engine fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the BFE service has failed to start. If you disable this service, then 5 other services will be unable to start (see the "Dependencies" section below).
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:
