Ran across an old server running server 2000 with a client. We have a new 2008 R2 box joined to the domain and ready for DCPROMO. It has been a while since working with 2000 server.
ADPREP from the 32 bit version of server 2008 disk
When I run DCPROMO an error occurs saying I need to run ADPREP /FORESTPREP
So I ran ADPREP again and the server 2000 box says it has already been run.
