Notes

To perform this procedure, you must be a member of the Schema Admins group in Active Directory, or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure. For more information, see Default local groups, Default groups, and Using Run as.
The Active Directory Schema snap-in must be connected to the schema master to perform this procedure. The Active Directory Schema snap-in connects to the schema master by default when it is started.
If the Active Directory Schema snap-in is not installed, see Other Resources.
Indexing an attribute improves the performance of queries run against the attribute.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
