Adding a Win2k8 Domain Controller to a Windows 2003 Native Domain

Hi,

I am just embarking on a bit of research to add the first Win2k8 Domain Controller to a Domain with 24 sites running in Win2k3 Native mode.  

Anyone perform this and have any pitfalls that they'd like to mention?  

Anyone have a great recipe (article) that they used to work through the process?

Thanks,
RP

What you need to do is prepare the Schema for the intergration of Windows Server 2008. You will need to run Forest/Prep and then also Domain/Prep.

You will also need to know which Server or Servers are holding the FSMO Roles. When you promote the Windows Server 2008 to a Domain Controller you will need to transfer the 5 FSMO Roles to the Windows Server 2008 DC.

The 5 FSMO Roles are the Schema Master Role, Domain Naming Master Role, the PDC Emulator, the Rid Master Role and the Infrastructure Master Role.

Make sure you do not raise the Forest Functional Level or the Domain Functional until all your Server are 2008 Level. If you raise the Forest and Domain Funtional Level to 2008 there is no going back.

Just to reitterate, the domain is presently running in Win2k3 native mode, OK... so this Win2k8 server will just be one of the DC's and Global catalog servers in a random site, since this site had the funds to swap out their server first.  However... this server will not be where the FSMO roles will live, so after I prep the schema in the forest and domain I want to leave the current Win2k3 servers that share the FSMO roles just as they are for a while. Probably another month or two until I get to them.  Anything wrong with that approach?  

Also, is it recommended to run the Forest and domain prep on any particular server?  For instance, the current Wink23 Schema Master roles lives on DC1 and the Infrastructure master live on DC2.  I recall reading something a while back that I should install the forest and domain preps on a server that holds the schema role for one and the infrastructure role for the other.

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

This would be ok. But you need to run the Forest/Prep - Domain/Prep on Domain Controller where the Schema Master Role and the Domain Naming Master Role reside.

The changes would then be replicated to all Domain Controllers in the Forest.

Looking for "more" details. Feel like the answered were rushed and could have been more comprehensive.
