Locked-Down Windows PCs

As described above, the Portal Server automatically downloads components to client PCs
depending on the Global Assignment setting. This download can be an issue in environments
that have restrictions on client software installation. For playback of WM files, Portal Server
uses the existing Windows Media Player components on the client PC and there is no need
for the extra components to be downloaded. This means that Portal Server and WM can be
used in some but not all restrictive or "locked-down" environments.

Even if downloads are configured, a client PC will still refuse to accept the component
download if the Internet Explorer security feature

Download signed ActiveX controls

disabled. When using Portal Server 4.0 exclusively with WM streams and a WM VOD, the
client PC can refuse to accept the downloaded components and all Portal Server features
except

Add Video

will work. In this case you should uncheck the

Add Video Utility

in Global

Assignments.

Some sites also require that their PCs be configured with certain Internet Explorer security
settings. The Portal Server will not work on clients with Internet Explorer security set to

will

work at any level at or below

. If you start at

, the

client will still work with Portal Server if you enable

Since firewalls on LAN client PCs can also cause problems with Portal Server, it is
recommended that firewalls be disabled on LAN clients. (In Windows XP with Service Pack
2, the firewall is enabled by default.) Portal Server's support for Internet clients is designed to
work through firewalls. If you have Internet clients with firewalls see the description of
LAN/Internet address ranges in Global Assignments on page 21.

Macintosh PCs

If configured with the appropriate components, Macintosh PCs (with Safari or Firefox)
can play all stream types including MPEG-1, MPEG-2, MPEG-4, and Windows Media.
(Intel-based Macintoshes play all streams

except

WM.) In a Macintosh environment, if

downloads are configured in Global Assignments, when you launch the ETV Portal Server
for the first time, the Home page (see Figure 2) displays a link prompting you to download
components that are appropriate for your computer. If you agree, these components are
automatically installed and no additional download is necessary for subsequent access. On
Macintosh PCs, Portal Server functionality is the same as in Windows except that the

Add

Video

feature is not available. Table 3 shows the stream types supported for each

environment; Table 4 shows the operating systems that are tested and supported. Note that
there are certain performance limitations in Macintosh environments; see the
