So I didn’t "really" notice this, but then Patrick mention it and I thought wot? Basically when you try and dcpromo the first Windows 2008 server in a Windows 2003 forestyou get this:
so you need to run Z:\sources\adprep>adprep.exe /forestprep but from an existing DC or you get this:
Z:\sources\adprep>adprep.exe /forestprep Adprep cannot run on this platform because it is not an Active Directory Domain Controller. [Status/Consequence] Adprep stopped without making any changes. [User Action]
Run Adprep on a Active Directory Domain Controller.
From an existing Windows 2003 DC
Z:\sources\adprep>adprep.exe /forestprep ADPREP WARNING: Before running adprep, all Windows 2000 Active Directory Domain Controllers in the forest should be upgraded to Windows 2000 Service Pack 4 (SP4) or later.
[User Action] If ALL your existing Windows 2000 Active Directory Domain Controllers meet this requirement, type C and then press ENTER to continue. Otherwise, type any other key and press ENTER to quit.

Adprep successfully updated the forest-wide information.
Then you to do a domain prep!
Z:\sources\adprep>adprep.exe /domainprep Running domainprep ... Adprep successfully updated the domain-wide information. The new cross domain planning functionality for Group Policy, RSOP Planning Mode, requires file system and Active Directory Domain Services permissions to be updated for existing Group Policy Objects (GPOs). You can enable this functionality at any time by running "adprep.exe /domainprep /gpprep" on the
Active Directory Domain Controller that holds the infrastructure operations master role.
This operation will cause all GPOs located in the policies folder of the SYSVOL to be replicated once between the AD DCs in this domain.
Microsoft recommends reading KB Q324392, particularly if you have a large number of Group policy Objects.
If you want to install read-only Domain Controllers
Z:\sources\adprep>adprep.exe /rodcprep

Now you can then resume promoting a windows 2008 server.

Just kidding! Thanks for the post!!
