By enabling this plug-in, you can customize how the server
handles internal events, authorizes specific events, or responds to
basic plug-in actions, such as enabling or disabling a plug-in by
using a scripting language (such as Microsoft JScript®, Microsoft
Visual Basic® Scripting Edition, or Perl Script).
The WMS Active Script Event Handler plug-in is
available only if Windows Media Services 9 Series is running on the
following editions of the operating system: Windows Server 2003,
Enterprise Edition and Windows Server 2003, Datacenter Edition. If
you are running Windows Server 2003, Standard Edition, this feature
is not supported.
