I have a 2003 Enterprise Edt. 32bit server as my primary DC and want to install a 2008 r2 Enterprise 64bit server as a secondary DC with a child domain.
When I run dcpromo.exe and follow the steps up to where it wants me to name the new child domain and click next, I get this error: To install a domain controller into this Active Directory forest, you must first prepare the forest using "adprep /forestprep". The Adprep utility is available on the Windows Server 2008 R2 installation media in the \support\adprep folder.
and follow the below link:
then its gives me the below error, could you please help me how to solve this issue ( coz before i had a backup domain controller Win Server 2003 Enterprise Edt. 32bit but now its no more its not working and i don't have backup also)
Before running adprep, all Windows 2000 Active Directory Domain Controllers in t
he forest should be upgraded to Windows 2000 Service Pack 4 (SP4) or later.
If ALL your existing Windows 2000 Active Directory Domain Controllers meet this
requirement, type C and then press ENTER to continue. Otherwise, type any other
key and press ENTER to quit.
Adprep was unable to extend the schema.
The schema master did not complete a replication cycle after the last reboot. Th
e schema master must complete at least one replication cycle before the schema c
an be extended.
Verify that the schema master is connected to the network and can communicate wi
th other Active Directory Domain Controllers. Use the Sites and Services snap-i
n to replicate between the schema operations master and at least one replication
partner. After replication has succeeded, run adprep again.
Please help me how to solve this issue.
