Hi all, I have been having much difficulty with exchange 2003. I have a forest containing two child domains also. AS FOLLOWS FDC1Forest Domain Controller 1 domain =net.local (GLOBAL CATALOG) FDC2 Forest Domain Controller 2 CDC1-1 Child Domain 1 (Domain Controller 1) domain = child1.net.local (GLOBAL CATALOG) CDC1-2 Child Domain 1 (Domain Controller 2) CDC1-1 Child Domain2 (Domain Controller 1) domain = child2.net.local (GLOBAL CATALOG) CDC2-2 Child Domain2 (Domain Controller 2) The Exchange server is ex.net.local and is a member server in the forest. When i create a exchange enabled user in (net.local) the user appears in the global address list. When i create a exchange enabled user in either of the two child domains the don't appear. This is the case both in outlook (2007) and owa. Replication checks ok, and i ran forestprep and domain prep on all domains before install. Can anybody help me or at least point me in the right direction? Im at my whits end! Thanks in advance. Cheers guys

Managed to fix it guys thanks anyways. There was no RUS policy for the child domain!
