IKE and AuthIP IPsec Keying Modules (IKEEXT) Service Defaults in Windows 8

The IKEEXT service hosts the Internet Key Exchange (IKE) and Authenticated Internet Protocol (AuthIP) keying modules. These keying modules are used for authentication and key exchange in Internet Protocol security (IPsec). Stopping or disabling the IKEEXT service will disable IKE and AuthIP key exchange with peer computers. IPsec is typically configured to use IKE or AuthIP; therefore, stopping or disabling the IKEEXT service might result in an IPsec failure and might compromise the security of the system. It is strongly recommended that you have the IKEEXT service running.

Default Behavior

IKE and AuthIP IPsec Keying Modules is a Win32 service. In Windows 8 it will not be started until the user starts it. When the IKE and AuthIP IPsec Keying Modules service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If IKE and AuthIP IPsec Keying Modules fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the IKEEXT service hasn't been started.

Dependencies

IKE and AuthIP IPsec Keying Modules can't start, if the Base Filtering Engine service is disabled or not available.
