My client has an NT4 server that serves as the domain of his small business. He recently enlisted me to help him migrate all of the information, which includes exchange, and traverse onto the windows 2000 server. What is the easiest way to do this. Is it possible to have them both on the same network, one being just a regular server, say, the small business server machine, transferring all of the information from the nt4 server that is needed and then promoting it to a domain controller?
