We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
When you use the Microsoft PowerPoint Animation Player with Netscape clients, you may get the following error message:

Netscape was unable to find a plug-in for

application/octet-stream.



CAUSE
If you use Netscape Navigator, the Web server must send the PowerPoint Animation files as a special type of file to avoid the above error message.



WORKAROUND
Ask your server administrator to add the following MIME mapping to the server:

.PPT -> application/mspowerpoint

.PPZ -> application/mspowerpoint

.PPS -> application/mspowerpoint

.POT -> application/mspowerpoint

If you use the Microsoft Internet Information Server (IIS), add the following registry entries on your server:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\InetInfo\Parameters\MimeMap]

application/vnd.ms-powerpoint,ppt,,5

application/ms-powerpoint,ppz,,5

application/ms-powerpoint,pps,,5

application/ms-powerpoint,pot,,5



MORE INFORMATION
For more information about adding MIME mapping, refer to the documentation for the particular server being used.
