HTTP Error 404 - File or directory not found. Internet Information Services (IIS)

Problem :

We come across this common exception when we try to open a file in IIS 6.0 or later web server for which MIME TYPE is not defined for the file extension.

Exception I Encountered Was :

HTTP Error 404 – File or Directory not found

#########################################################################################

Solution :

Define a wildcard "MIME Type" within the roaming user profile directory of the IIS server. Steps to define the wildcard "MIME Type" :

• Click "Start > Control Panel > Administrative Tools".
• Double-click on "Internet Information Services (IIS) Manager".
• Right-click on the roaming user profile directory that has been created.
• Select "Properties".
• Select the "HTTP Headers" tab.
• Click the "MIME Types" button.
• Click the "New" button.
• Type "*" in the "Extension" field:
• Type "application/octet-stream" in the "MIME type" field:
• Click "OK" to apply the new MIME type.
• Click "OK" again to apply the new settings.

Note:

• In the example above, IIS now serves files of all file extensions.
• In order for the changes to take effect, the "World Wide Web Publishing Service" must be restarted, or just wait for the worker process to recycle.
• This information can also be referenced within the "Dragon NaturallySpeaking IT Administrators Guide" under "HTTP Roaming Settings".
