Please check the details from the latest Event 2080, which should be logged in the application log every 15 mins. The event will tell if the new DC/GC has been discovered properly Is DC-Prod02-VM a primary domain controller (PDC)? By default, DSAccess chooses the PDC to handle requests in exchange (KB 298879) And also, I assume that you haven’t installed exchange 2007 server on the DC, right?

James, Yes in the Event ID 2080 I can see all of the new and old GC have the same CDG records DC-Prod02-VM is the old DC/GC and has no role anymore, the new PDC is on the new Windows Server 2008 of course not, the Exchange Server is installed on dedicated VM for sure./* Server Support Specialist */
