Hi GabicusC,

You can not perform inplace upgrade from 32-bit OS to 64-bit OS. You would have to setup up second domain controller on 64-bit OS and the transfer GC role and FSMO roles to new server if you are thinking of decommissioning old DC.

Toni,

Thanks for the reply.  I have a 64 bit server already to go I am having an issue preparing the 32 bit Active Directory to go into my 64 bit server.  The tool that I have to prepare this is on the 64 bit server and I am not able to access the 32 bit server.

I agree with toniur. Basically, Active Directory itself is not 32- or 64-bit, in fact you can have both 32- and 64-bit DCs in your domain without a problem. What is 64-bit is the server OS and processor which you install; obviously there are many advantages to using a 64-bit OS, but both 32 and 64 bit DCs and member servers can co-exist in the same domain without problems, just dcpromo them as usual and AD info will come across from your existing DC(s).

Which tool are we talking about? ADprep? Do you have 64-bit OS Server R2? You should find 32-bit adprep and run it on your first DC if this is your problem.

We have one client using a Windows NT Server as a PDC, Windows 2003 32-bit and a Windows 2003 x64 domain controllers.

Yes, they all work together. :-)

Transferring roles - you'll find these helpful

If your thinking Exchange 2007 (NT server must be properly removed from active directory).

Before adding a 64-bit domain controller into an Active Directory that already contains a 32-bit DC, you'll need to run the 64-bit version of adprep /forestprep and adprep /domainprep from the 64-bit media.  Once this is done, you can add a 64-bit DC as an additional DC in an existing domain as normal.
