Hi there, I have 2 DCs.
First DC1 is windows server 2008 32bit. holds FSMO.
Second DC2 is additional domain windows server 2003 which was before the master schema.
I have to move this old server "DC2" to be used for something else So I am planning to add additional domain Windows Server 2008 R2. I am confused and totally forget how i did this before If I add this additional domain do I have to prepare the current DCs with adprep /forestprep OR adprep /domainprep /gpprep. Please advise. Note that we have only single site and one domain.

If you plan on updating your forest and domain to W2K8 do this:

D:\sources\adprep>adprep /forestprep
D:\sources\adprep>adprep /domainprep
D:\sources\adprep>adprep /domainprep /gpprep

You can transfer the roles using ntdsutil:

ntdsutil
role
connection
connect to server DC#
quit
transfer role schema master
transfer role naming master
transfer role pdc
transfer role infrastructure master
transfer role rid master

As you state that you ALREADY have a 2008 server acting as a DC then you do not need to do any forest/domainprep at all.

Just setup a new 2008 server and join the domain and run DCPROMO

You should also raise the domain functional level to 2008 after performing dcpromo.

Also bear in mind that one server should be global catalogue and the other host FSMO roles.

Have both DCs be global catalogs.  No reason not to when they are on the same LAN.

Once you've added the new domain controller following instructions above, you can then demote the Windows 2003 domain controller.
It will then just be another member server, so you can re-use it for something else.
