If you are trying to add a machine to the domain as a DC and it is running a later version of windows than your existing DCs, then as it says, you need to run adprep.

Take the CD/DVD from the new server, put it in one of the existing DCs - preferably the one holding the Schema Master role.

If the CD/DVD autoruns then cancel the operation. On the CD/DVD find the SOURCES folder, from there run

Adprep /forestprep

allow replication to happen then run

Adprep /domainprep


(if your current DC is 32bit use Adprep32 instead of Adprep)

Once this is done you can remove the CD/DVD and then go back to the new machine and run DCPromo again.

The addprep process is essential if you are adding a new DC that has a schema version that post-dates the schema that is in place.

would running dcpromo from the existing win3k3 std pdc transfer all roles to the new win08 r2 ent pdc?

FSMO roles don't move during a DCPROMO.
Only when you create a new dc in a new domain are FSMO roles added by the DCPROMO task.

When transfering roles from one DC to another, you need to initiate the move yourself through transfer/seizing the roles.
Using NTDSUTIL
