So I have a small domain, 1 forest, 1 domain - maybe 10 users / computers.  I am looking to replace their DC (Windows 2003) with a new server, (Windows 2008 R2).  

So I got my new server all fired up and patched.  I joined it to my existing domain.  Then the AD DS role was installed on the new server.  

Then, I raised the forest and domain functional level from Windows 2000 native to Windows 2003.  Then, on the 2003 DC, I ran adprep /forestprep, adprep /rodcprep, and adprep /domainprep /gpprep.

Once this completed, I tried to run dcpromo on the 2008R2 dc and it will not complete.  I am selecting adding it to an existing domain in an existing forest, but it keeps telling me that I need to run adprep /forestprep in order to continue.  I am a bit stuck - I haven't gone through the process of 2003-2008 in a few years now so I feel like I am missing something.

Any help is appreciated.

Thanks

Can you check the log from%\Debug\adprep\logs\yyyymmddhhmmss\adprep.log ?

Where you run the adprep so you will get the status whether adprep done successfully or not.
