How to Start/Stop IKE and AuthIP IPsec Keying Modules service

Service name: IKEEXT

Display name: IKE and AuthIP IPsec Keying Modules


Description:

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.
