  • Modifying the schema is an advanced operation best performed by experienced programmers and system administrators. For detailed information about modifying the schema, see the Active Directory programmer's Guide at the Microsoft Web site.


  • To perform this procedure, you must be a member of the Domain Admins group or the Enterprise 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.

  • You can also run the Active Directory Schema snap-in from a computer running Windows XP Professional. Simply install the Windows Server 2003 Administration Tools Pack on the computer, and then complete step 9 above.

  • The Windows Server 2003 Administration Tools Pack cannot be installed on computers running Windows 2000 Professional or Windows 2000 Server.

Information about functional differences

  • 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.
