We I have a domain with several W2000 and W2003 servers. When attempting to run dcpromo on a new W2003 server, a message appears stating the need to run ADPREP. When attempting to run ADPREP (the new version from R2) from this server, it tells me ADPREP cannot be run from this platform because it is not a domain controller. I brought up the other W2003 servers a while back and thought I ran ADPREP on them at the time. What am I doing wrong here?
