thanks for the information. I have reviewed the document that accompanies the utility and all i can say is this looks like a good deal of work! Here is our situation - we have 2 server which are both DC's of a domain. These two servers are from an old company and are now going to be used at a new company. Therefore, we would like to use a new local domain name. We heard about the domain rename utility so we figured that we would research this. My question is, might it be better off for us to just demote both DCs and promote them and in the process create the new domain? These servers aren't actually in production right yet. The one server is an exchange 2003 server so I am thinking at worst we may just need to reinstall exchange. Yet another idea I was pondering was to just start from scratch - in other words, back up the servers, format them and start all over. Any suggestions would be greatly appreciated!
