Child Domain

[Encino40]

Just created a child domain. I know that I need to run setup /pd on the Child domain. Every time I try it fails. I tried logging in as the Administrator of the child domain and the root domain. Both fail.
E:\>setup /pd

Ok the setup /pd worked. I forced replication again and it worked. Now when I go to EMC and do a new mailbox I see the users in the child domain but when I try to create the mailbox I get:
Summary: 1 item(s). 0 succeeded, 1 failed.

Sorry Last update. I am just a little confused. In the EMC if I go to Recipients Container I only see users from the root domain. If I then go to Modify Recipient Scope and change the global catalog to the child domain I then see users from root domain and child domain.

My question is if I had 5 child domains I would have to go to Modify Recipient Scope and do that for each child domain?
