Adprep.exe is a command-line tool that updates permissions as necessary to prepare a forest and domain for a domain controller that runs the Windows Server® 2008 operating system. (http://technet.microsoft.com/en-us/library/cc731728.aspx)
If adprep.exe was not installed on master domain controller server, it can be found on the second Server 2008 disc "drive:\support\adprep\". NOTE: Run adprep32.exe for x86 systems
From the command line, use the following commands on the on root domain controller
"adprep.exe /forestprep"
Prepares a forest for the introduction of a domain controller that runs Windows Server 2008
"adprep.exe /domainprep"
Prepares a domain for the introduction of a domain controller that runs Windows Server 2008.
"adprep.exe /domainprep /gpprep"
Performs similar updates as domainprep. However, this command also provides updates that are necessary to enable Resultant Set of Policy (RSOP) Planning Mode functionality.

Once adprep is complete on the root domain controller, server roles will need to be migrated as well.
Use the following commands :
To view replication of DC use: dcdiag /test:replications /v
To show successful replications: repadmin /showrepl
