Server 2008 as domain controller in 2003 domain
Posted on 2008-06-20
I currently run Server 2003 domain.. 2 DCs.
I have aquired server 2008, and am trying to promote the server to DC.
i have run adprep /forestprep
adprep /domainprep on the schema and infrastructure master (1of the DCs).
However as I try to dcpromo the server 2008, I get the message:
"to install domain controller into this active directory forest, you must first prepare the forest using adprep /forest prep"
I have looked through the debug logs, and
"Log on to the schema master primary for this forest, run the following command from the installation media to complete the forest update first:
and then rerun adprep.exe /domainprep on infrastructure master again. "
I do this, however I am still unable to promote server 2008.
Server 2008 is 64 bit.
Server 2003 DCs are 32 bit (1 DC is a global catalog), the other the primary infrastructure and schema server.
