I previously had Exchange 2007 on a Windows Server 2008 x64 machine (not R2). I migrated everything to Exchange 2010 and uninstalled Exchange 2007.
I want to use this server as another DC. My question is, how should I go about this?
Should I remove the server from the domain, rename it, rejoin and go from there or should I remove the server from the domain, reformat it, reinstall windows, rejoin and so on.
I want to make sure I have the right method before starting the process.
