Adding Server 2012 Domain Controller to Existing 2003 Domain

I have a single server 2003 32bit domain controller not R2.  I am trying to add a second domain controller with Server 2012 with a view to retiring the first 2003 domain controller.

I am getting these errors when I try to add the new server as a DC.

Adprep could not retrieve data from the server myserver.mydomain.co.uk through Windows Managment Instrumentation (WMI).
[User Action]
Check the log file ADPrep.log in the C:\Windows\debug\adprep\logs\20130624171731-test directory for possible cause of failure.

Adprep encountered a Win32 error.
Error code: 0x5 Error message: Access is denied.

Adprep failed while performing Exchange schema check.
[Status/Consequence]
The Active Directory Domain Services schema is not upgraded.
[User Action]
Check the log file ADPrep.log in the C:\Windows\debug\adprep\logs\20130624171731-test directory for possible cause of failure.

Adprep encountered a Win32 error.
Error code: 0x5 Error message: Access is denied.


I have tried these fixes but no success...

have you run adprep from command line with "run as" permission?

On which machine should this be run.  There is no 32bit adprep available for server 2012 to run it on the server 2003

Have a flick through this MS link on troubleshooting ADPrep errors.

http://blogs.technet.com/b/askds/archive/2008/12/15/troubleshooting-adprep-errors.aspx

2012 automatically finds the Schema Master so you don't have to run adprep from that specific box (generally speaking!).  That said, I've only tested that in a domain running 2008 R2 (64bit) so whether that works with 2003 32bit I can't confirm.

All:

None of these things helped I'm afraid.  I have now resolved the Server 2012 DC Promo issue by adding a virtual server with Server 2008R2 and transferred all the FSMO roles across to this server and then running the Domain Controller Promotion Wizard on the Server 2012 with success at last.  I shall now transfer the FSMO roles to the Server 2012 machine and then demote the 2003 server and then finally the Server2008 virtual server.  I'll keep you posted how it goes...

I have completed the task

The old server is now demoted and gone and the intermediate 20008R2 server is now demoted and gone leaving me with just the server 2012 DC.

Thanks for your input though everyone.

No other suggestions worked and I don't believe now it could have worked after looking at more and more articles I found on the subject

This happened to me, I was able to fix by going into Component Services on 2003 server, right click 'my computer', properties, on 'default properties' tab 'enable distributed COM on this computer' was unchecked.  I checked it and reboot both servers, I was then able to promote the 2012 server to DC, adprep went thru with no issues.

Hope this helps someone else, I was not able to find this fix from MS or any google search... had to run wmidiag.exe which showed dcom disabled on 2003.

SBSDan: Thanks for that comment.  I'll bear that in mind for next time I have the same scenario, it certainly would have saved me time.

The answer to this is found here. http://www.kickassnetwork.net/?p=431 WMI is the issue. Follow the WMI guidelines and once repaired, promotion is straightforward. I hope I save someone the hours it took me to find this.
