SUMMARY

The Windows 2000 schema contains a large number of object attributes that administrators can use. The attributes typically required by Windows 2000 are enabled by default when the first domain controller is installed; a number of these attributes are used by both Active Directory and the global catalog (GC). These attributes have the Index this attribute in the Active Directory and Replicate this attribute to the Global Catalog options selected in their properties.

You can change both the number of attributes selected and which specific attributes are used by using the Active Directory Schema snap-in in Microsoft Management Console (MMC). However, in most cases, there is no need to modify any of these attributes. Carefully consider any changes to these default settings before making changes.

NOTE: You should make changes or additions to the schema only after careful consideration and planning. After you make additions, you can only disable them (you cannot delete them). Additional attributes may increase the time required for their replication.
