Introduction

"HTTP Error 404 - File or Directory not found" error message when you request dynamic content with IIS 6.0

Description

When you request dynamic content such as an Active Server Pages (ASP) page, an ASP.NET page, an Internet Services API (ISAPI) application, or a Common Gateway Interface (CGI) application on a Microsoft Windows Server 2003 server that is running Internet Information Services (IIS) 6.0, you may receive one of the following error messages:

Error message 1

HTTP Error 404 - File Not Found

Error message 2

HTTP Error 404- File or Directory not found

Solution

To permit IIS to serve content that requires a specific ISAPI or CGI extension that is already listed in the Web service extensions list, follow these steps:

1. Open IIS Manager, expand the master server node (that is, the Server name node), and then select the Web service extensions node.
2. In the right pane of IIS Manager, right-click the extension that you want to enable. In this example, this is Active Server Pages.
3. Click to select the Allow check box.
