Exchange 2013 Install Readiness check problem

Question

We have a test environment which was 2008R2 AD.  We properly went through the migration path and are currently at 2012R2 Active Directory functional level.
I'm installing Exchange 2013 with Sp1 into the domain.  I have successfully prepared the domain as outlined on technet, and verified its success with the logs and looking in ADSI edit.  No errors.  All seems to have ran correctly.
When I attempt to install the first exchange mailbox server, the Readiness check fails saying "the local domain needs to be prepared using Setup /PrepareDomain before server roles can be installed"...  1 forest, 1 root domain, 1 child domain.
 The account I'm using is a member of Schema Admins, Enterprise Admins, Domain admins etc.  
Has anyone else come across this or have any suggestions?

Answer 1

Thanks for the replies.  Yes, replication has occurred.  We have 2 DC's in the root, and 2 DC's in the child.  After each prepare I ran "repadmin /syncall", each time completing successfully.  I also verified the settings in
ADSI edit, and all match up correctly to the chart.  The exchangesetup logs indicate each prepare runs successfully.
I have also rebooted all 4 DC's and the Exchange server I'm trying to install.  I have verified the record in DNS.  Where is the script that the Readiness check is running?  I may look into taking that check out of the script!
Also, looking at the exchangesetup log, it is showing different information in it than before (same error on the GUI screen).
