Figure 85 Installer for Schema Extender and snap-ins
You cannot run the schema installer on a domain controller that hosts Windows Server 2008 Core.
For security and performance reasons, Windows Server 2008 Core does not use a GUI. To use
the schema installer, you must install a GUI on the domain controller or use a domain controller
that hosts an earlier version of Windows.
Schema Extender
Several .xml files are bundled with the Schema Extender. These files contain the schemas that
are added to the directory. Typically, one of these files contains a core schema that is common to
all of the supported directory services. Additional files contain product-specific schemas. The schema
installer requires the .NET Framework.
The Schema Extender installer includes three important windows:
•
Schema Preview
•
Setup
•
Results
Schema Preview window
The Schema Preview window ( Figure 86 ) enables the user to view the proposed extensions to the
schema. The installer reads the selected schema files, parses the XML, and displays it as a tree
view. It lists all details of the installed attributes and classes.
