Hi,
I am receiving an error when trying to promote a Windows 2008 R2 or a Windows 2012 R2 server to be a Domain Controller in an existing Windows 2003 (SP2) domain. I have tried both 2008 R2 and 2012 R2 and receiving the same error.
Existing Environment:
2 x Windows 2003 SP2 Domain Controllers
Several "External" trusts
Windows Server 2003 functional level
New Windows 2008 R2 and Windows Server 2012 R2 servers (with DNS pointing to existing 2003 DC's which are DNS servers)
The error:
The promotion errors with the following in the ADPREP.LOG file.
Adprep was unable to complete because the call back function failed.
[Status/Consequence]
Error message: Unable to access the computer "DomainControllerName.domain.com.au". Access is denied.
(0x80070005).
[User Action]
Check the log file ADPrep.log, in the C:\Windows\debug\adprep\logs\20140207153306 directory for more information.

Adprep was unable to update forest information.
What have I tried so far?:
- Ensured account being used was part of Enterprise Admins group, Domain Admins Group and Schema Admins group. Also created a new AD account that ONLY belonged to those 3 groups.
- Disabled antivirus on source domain controller (the one referenced in the error)
- Ensured Windows Firewall was turned off on the source and target DC's
- Ensured AD account being used was part of the Administrators group in the domain
- Ensured Administrators had trusted delegation rights in Domain Controller Policy
- Ran ADPREP /forestprep and /domainprep /gpprep using Windows 2008 R2 media on the existing 2003 DC (successful)
- Tried doing DCPROMO (using Server Manager) on both a Windows 2008 R2 and a Windows 2012 R2 server. Same error on both servers.
- Checked Event Logs for anything obvious, but nothing I could see.
- Searched the net high and low for something to go on but can't find anything!!
Hope someone can help here! Luckily I cloned all these servers and am doing this in a test environment. (Both 2003 DC's which are also DNS servers, 2008 R2 target DC, 2012 R2 target DC, Exchange 2003 server and target Exchange 2010 server that will happen
after DCPROMO).
