MORE INFORMATION

You see these errors in a situation where you have a root domain, and a child domain that both have Global Catalog Servers. When you run the setup /forestprep command from the Exchange media in the root domain, during the replication process between the root, and child domain, you may see these errors logged in the application event log on the servers in both the child and the root domains.

This behavior occurs because the schema is imported in an order other than superclass inheritance. When a class is imported, superclass attributes point to other classes. Because these may not have been imported yet, you see these errors in the application event log.

You can safely ignore these errors.
