IIS 6.0 F1: New Web Service Extension

Applies To: Windows Server 2008 R2

In an effort to reduce the attack surface of your Web server, IIS 6.0 serves only static content after a default installation. Programmatic functionality provided by IIS APIs (ISAPIs) or Common Gateway Interfaces (CGIs) must be manually enabled by an IIS administrator. ISAPIs and CGIs extend the ability of your Web pages and for this reason ISAPIs and CGIs are referred to here as Web service extensions. For example, in order to run Active Server Pages (ASP) with this version of IIS, the ISAPI Asp.dll must be enabled as a new Web service extension.

Use the options in this dialog box to enable or disable specific ISAPIs or CGIs.

noteNote
ISAPI filters are not considered Web service extensions. ISAPI filters are not enabled through this dialog box.

noteNote
For a Web service extension to run, the ISAPI or CGI must be located in the content directory on your server running IIS (for example, LocalDrive:\Inetpub\wwwroot for a default installation).

Extension name

Type the friendly name of the ISAPI or CGI (for example, Microsoft® FrontPage® Server Extensions).

Required files

This is a list of all of the ISAPIs or CGIs required for the Web service extension to run. For example, FrontPage Server Extensions is composed of five files and all five files need to be enabled before you can begin extending Web pages with FrontPage Server Extensions.

Add

Click to select required files.

Remove

Click to remove the currently selected file from the list.

Set extension status to Allowed

Select to allow the Web service extensions to run on your server. Clear this option to prohibit Web service extensions from running on your Web server. For example, by entering Nimda.dll information in this dialog box and then setting the status to Prohibit (status when option is cleared), you prohibit Nimda.dll from running on your Web server.
