IKE and AuthIP IPsec Keying Modules

 

General Information

None at this time

Windows 8

Default 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.

Additional Information

If you use an external hardware firewall/gateway/router between your computer and the internet, do not use IPsec (VPN tunneling, etc) and Internet Connection Sharing (ICS), then this service and the following group of services can be disabled:

I highly recommend that you do not disable the Windows Firewall unless you use a different software firewall or external hardware solution, but the services listed above are all involved with each other.
