IIS mime ing When IIS can browse all files with extension
You can only add wildcard ing to IIS mime ing during troubleshooting as a temporary solution. After you confirm that the MIME type is missing, delete the wildcard ing and add a specific mime ing of the MIME type to be processed.
1. Open the IIS Microsoft Console (MMC), right-click the name of the local computer, and click "properties ".
2. Click "MIME type ".
3. Click "new ".
4. In the "extension" box, type an asterisk (*).
5. In the "MIME type" box, type application/octet-stream.
6. Apply new settings. Note that you must restart the Web Publishing Service or wait for the workflow to take effect.
Note: In addition to making the above changes on the global layer of IIS, you can also add the required MIME types to the lower layers of the metabase. In this case, you can specify a site or directory with a specific file extension, rather than allowing all sites to process the extension globally.

C. The PHP interpreter should be c: \ winnt \ PhP4 \ php4isapi. dll.
