SYMPTOMS

Server Error in Application &quot; &quot;

HTTP Error 404.4 - NO_HANDLER

Description: The system cannot find the file specified.

Error Code: 0x80070002



CAUSE
The file name extension of the requested URL does not have a handler that is configured to process the request on the Web server.



RESOLUTION
To resolve this problem, add a handler mapping for the file name extension of the requested URL. For example, follow these steps if you want to add a StaticFile handler mapping:
 * 1) Start IIS Manager. To do this, click Start, click Run, type inetmgr.exe, and then click OK.
 * 2) In IIS Manager, expand  , expand Web sites, and then click the Web site that you want to modify.
 * 3) In Features View, double-click Handler Mappings.
 * 4) In the Handler Mappings pane, right-click the StaticFile handler mapping, and then click Edit.
 * 5) In the Edit Module Mapping dialog box, type * in the Request path box, and then click OK.

Note After you follow these steps, you can successfully visit static files. For example, you can successfully visit files that have the following file name extensions:
 * .htm
 * .html
 * .jpg
 * .gif
 * .png
