I have a 2003 r2 standard 32bit server as my primary DC and want to install a 2008 r2 standard 64bit server as a Additional Domain Controller 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. The thing is, I keep getting this message even though I run "adprep /forestprep", "adprep /domainprep", and "adprep /domainprep /gpprep" on my primary DC.
Please find the attached snap shot and command line error that I face when going to create a new Additional Domain Controller
|OS||DNS Service Installed||Active Directory Installed||IP Address||DNS IP|
|DC||Windows Server 2003 Standard||Yes||Yes||192.168.1.10||192.168.1.10|
|ADC||Windows Server 2008 Standard||Yes||Yes||192.168.1.9||192.168.1.10|
Error arise on both case on ADC i.e.
1. Without Joining to DC
2. With Joining to DC
