www.BlackViper.com: Windows Vista SP1 Services 411 - IKE and AuthIP IPsec Keying Modules

IKE and AuthIP IPsec Keying Modules

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:

• Base Filtering Engine
• IKE and AuthIPsec Keying Modules
• Internet Connection Sharing (ICS)
• IPsec Policy Agent
• Routing and Remote Access
• Windows Firewall

I highly recommend that you do not disable the Windows Firewall, but the services listed above are all involved with each other.
