Issue/Introduction

Package downloads containing specific file types (such as .bat files) may fail. The Symantec Management Agent logs display the following error:

HTTP status 404: The requested URL does not exist on the server or the server is down (0x8FA10194)

Further examination of the IIS log files on the server shows an extended HTTP response status of 404.3.

Environment

ITMS 8.x

Cause

An HTTP Error 404.3 - MIME Type Not Configured occurs when IIS refuses to serve a file because its extension is not registered in the site's or server's MIME Types configuration. By default, unmapped file extensions like .bat are restricted from download.

Resolution

To resolve this issue, add the file extension to the MIME Types in IIS:

1. Open IIS Manager and select the affected website or application pool folder (e.g., Default Web Site).

2. Double-click the MIME Types feature in the center pane.

3. In the right Actions panel, click Add...

4. In the File name extension field, enter .bat (or the extension causing the issue).

5. In the MIME type field, enter text/plain or application/octet-stream.

6. Click OK.

7. Open Command Prompt as Administrator and run iisreset (or restart the specific web site).
