Hi all, This may be lengthy but I want to make sure I do not miss anything. We currently have Exchange 2000 running on our root domain controller. There is a request to install Exchange on a new server. Here is our setup: CURRENT SETUP: - Exchange 2000 (SP2) running on root domain controller which has DNS, DHCP installed - GFI Mail Essentials installed - NAV for exchange installed - Exchange server behind ISA 2000 which publishes OWA WHAT WE WANT TO DO: - Move Exchange 2000 to new server + GFI + NAV with the least amount of impact to Active Directory and Outlook client. What is the best approach? I am trying to do the planning for this and want to have all possibilities and eliminate as many head aches as possible. Thanks, Scott
