- The resource being accessed does not have read access set (through IIS). For example, the SCRIPTS directory does not have read access by default.
- The default document specified is either not correct, or the default document does not exist. For example, the default document may be set to Default.htm, but the one uploaded by the Web publisher is Index.htm. If a file named Default.htm is not on that Web site, this error message occurs.
- Directory browsing is not enabled when it should be. For example, if you have a Web site configured to show a directory listing (all files in the name space you are accessing), and directory browsing is not enabled, this error message occurs.
