I have 2 domain controller in my windows 2000 AD domain. Both are windows 2000 Server. I would like to add a windows 2003 domain controller and remove one of my windows 2000 domain controllers. I've done research on the exchange 2000 mangled attributes that occur when adding a windows 2003 server domain controller. My question is: Do I run the adprep /forestprep command and the /domainprep command on windows 2003 server that I would like to be an additional domain controller? or from the Forest Root? Does it matter that I have my windows 2000 in Native mode?
