Installing additional domain controller from Server 2008 to 2008 R2

Hi,

I'm having an issue installing an additional domain controller on a Windows Server 2008 domain (server is 32bit). The new server is a server 2008 R2 (64bit)

I have tried to run the adprep /forestprep and adprep /domainprep on the current domain controller with the Server 2008 (32Bit) media but the message is coming up that the information has already been updated.

When I go to dcpromo the new server 2008 R2 it comes up with message saying that I need to run the adprep.  

The new server is part of the domain and this shouldn't be a replication issue as nothing has been run.

any ideas?

Thanks,

Pete

Hello,
As the new DC is running a 64 bit OS you will need the 64 bit media to run ADPREP.
Please run this using the correct media and then you will be able to DCPROMO.

2008 R2 *does* include schema changes from 2008. So you must run adprep from the 2008 R2 media, not from 2008 media as you described.

Ok. So tried running adprep from the 2008 R2 media on both servers.

2008 - unable to run due to compatibility (32 + 64bit)

2008 R2 - needs to be run on a DC error message

And you are running adprep32.exe from the 2008 R2 media *on* the 2008 domain controller?  Can you post the specific output?

running adprep /forestprep and adprep /domainprep

Just ran the adprep32 and that worked.

Thankyou!
