Fixing 404 Errors
When Vector HelpDesk is installed on a Windows Server 2003 system, users may get 404 errors (File not found) when trying to open attachments. This is because IIS 6.0 on Windows Server 2003 only accepts requests for static files with extensions that it recognizes. You can prevent this problem by adding the extensions to MIME Types settings of the IIS server.
To define a MIME type for a specific extension:
1 Open Internet Information Services.
2 In the console tree, right-click the virtual directory used for attachments, then click Properties.
3 On the HTTP Headers tab, click MIME Types.
4 Click New.
5 In the Extension box, type a file name extension (for example, ini).
6 In the MIME Type box, type the MIME type of the file (for example, text/ini).
7 Apply your changes.
Notes
You
may need to restart the World Wide Web Publishing Service before your changes take effect.
For
more information on MIME types, see MIME Types in the IIS 6.0 Manager Help.
The
URLScan tool can also be configured to block processing of certain file name extensions. Verify these
settings.
