Failed to install active directory domain services binaries. The error was : The requested operation failed. A system reboot is  required to roll back changes made.
I am also getting the same error message and i am using Windows Server 2008 R2 (only available in x64 ). So what should i do to rectify this error without reinstalling the OS. I want to make it a domain controller.

Thanks and Regards,
CryptBala.

Hi,

Did you run "dcpromo" directly or run Server Manager to install AD role?

Please open %SystemRoot%\Debug folder, find Dcpromoui.Log and Dcpromo.log (if exist) and use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the file and then give me the download address.

Thanks.

For anyone who also searches for a solution for this, set the  Remote Registry Service to start automaticly if you disabled it. Reboot and run dcpromo again. Worked for me ;-)

SOLVED ::

First of all You need to add ADDS role from Server manager and then need to run dcpromo.exe from command prompt.

No need to take so much pain. Just go to C:\Windows\WinSxS and delete the file called "pending.xml", Reboot the server and try demotion - it will succeed.
