Windows 2008 R2 method for adding ISAPI extensions for IIS

Problem:

Part of the webmaster in the installation of the Guardian, there may be a window. "Setup has detected that your server IIS does not have an ISAPI extension turned on, please verify and continue the installation", prompting the host defender to fail

The ISAPI extension feature is turned on as follows:

Step1: in the Control Panel, select Turn Windows features on or off.

Step2: in the Service Manager, select Role, and in Web server, locate the ISAPI extension in the Role Services list.

step3: If "isapis extension" is not found, the instructions are not installed, click "Add role Service" in the upper left corner to add.

OK so our ISAPI component is installed, the same CGI component is installed here, you can take a closer look at it, very simple oh.
