This may occur after you upgraded from Release Candidate 2 (RC2) to the
Release to Manufacturing (RTM) version. Specifically, you did not re-run
forestprep with the RTM version of Exchange 2000 Setup. As a result, the
msExchUSRAccountControl attribute was not added to the schema. This is a
required attribute that was added post-RC2.
After you run /forestprep, which forces replication to the child domain, run
/domainprep in the child domain, and rebuild the Recipient Update Service
objects. Then you can log on to your mailboxes.
