We are trying to transition from a Win2k3 AD (single DC) to a Win2k8 AD by
adding a Win2k8 server to the domain (ie running DCPromo). First we ran what
we believed to be the updated version of ADPrep (with four options including
forestprep, etc...) on the Win2k3 DC but that update failed as it said the
update was only for the x64 version and not for the x32 version. So we ran
the ADPrep from the Win2k3 disk and everything came back either fine or it
stated it did not need to be run.

But when we run DCPromo on the Win2k8 server it says that ADPrep /forest
prep must be run on the source domain (again, ADPrep /forestprep states it
has already been run on that domain when we try to run it again). Are we
using the wrong ADPrep tool (which we downloaded from Microsoft) ? Should we
be running the ADPrep on the Win2k8 disk on the Win2k3 server ? Or did we
perhaps miss a step ?

TIA for any help on this one ...

Hello E-Double,

On the 2003 DC with the schema master FSMO, with a single domain controller
of course that 2003 machine, insert the 2008 installation disk and run the
adprep /forestprep, adprep /domainprep and adprep /rodcprep from the installation
disk direct with an account that is member of the schema admins.

Open a command prompt and go to E:\sources\adprep (where E: is your disk
drive) and run the adprep commands from here.

Best regards

Perfect, thanks ! We were really not sure what to try next, but this sounds
like it should fix it.

Tks,

Hello E-Double,

If you still have problems, please post the adprep logfile from C:\WINDOWS\debug\adprep\logs

If you like you can also copy the \sources\adprep to the 2003 dc and not use
the cd.
