Hi Everyone. I'm really stuck with this so hope someone can help. We have a crashed Server 2003 that I can't get back on line that housed Exchange 2003. We are trying to install Exchange 2010 on a new server but it keeps saying it can't as there is already a server with Exchange 2003 on, which is in mixed mode and doesn't have service pack 2 installed. I can't bring this old server back online. It has already been demoted and removed from the network, all FMSO roles have been seized and I have gone through the article supplied by Microsoft to Forceably remove the Exchange server. I can't see any reference to it or Exchange anywhere in Active Directory, ADSiedit, sites and services and no services are running. All references have been removed from the registry too. Am I missing something? Can someone please help? Thanks in advance. Andy
