Hello I have a domain with an unique DC is a 2003 R2 32bit, the Forest and Domain level is 2003.

I have joined a 2012 server to the domain.

I want to elevate the 2012 server as Domain Controller.

I have inserted the 2012 DVD in the 2003R2 machine to perform the "adprep /forestprep" but when I run the command I get the error:

the image file adprep is valid but is for a diferent kink of machine.

What is the problem?

Thanks

the problem is that 2012 is 64bit and windows 2003 is 32bit; can't run a 64bit executable on a 32bit operating system

with 2012, you don't need to run adprep on the 2003 server; it will do it automatically (a change from previous windows versions)

In Windows Server 2012, Adprep.exe is integrated into the AD DS installation process and runs automatically as needed.

Thanks,

I was trying the  adprep becouse when I try to promote the 2012 to Domain Controller I get the error:

can not create a delegation to this DNS server authoritative for the parent zone is not
or does not run Windows DNS server.

Can you help me or close this question and open another.

Thanks again.

ignore the error and continue

might only be an issue if you have multiple domains but if the 2003 server is functioning properly and registering the SRV records then you can safely ignore that message
