Hi all, I wonder if any of you have encountered this problem and can advise my best course of action: I have an Exchange 2007 Standard Edition server in a single domain environment, running on Windows Server 2003 R2 x64. There was a Windows Server 2003 domain controller with all the FSMO roles and was a Global Catalog server, which I was hoping to decommission.
So I dcpromo'd and transferred the FSMO roles to a new domain controller and I am happy that all the replication has occurred and the new DC is fully functional according to all Microsoft's tests. ( http://support.microsoft.com/kb/816106) However, on my Exchange server, the old domain controller is still listed in the following places: Microsoft Exchange \ Server Configuration \ Server Properties \ "System Settings" tab \ Active Directory servers \ "Domain controller servers being used by Exchange" & "Global catalog servers being used by Exchange". So I shut down the old DC and almost immediately Exchange stopped working (mailboxes unavailable, no OWA, no services, nothing). As soon as I brought the old DC back up, Exchange worked again. The next step was to shut down the old DC, then restart the Exchange services, but they failed to start. I tried a reboot of the whole server, which then hung on "Applying computer settings". As soon as I brought the old DC back online and then rebooted the Exchange server, everything was fine. As you know, the "Domain controller servers being used by Exchange" & "Global catalog servers being used by Exchange" settings in the above location are not configurable. My question is this: how can I make my Exchange server move on into the brave future with me and the new Domain controller? I really do need to decommission the old one. All help gratefully received. Many thanks and kind regards, Andrew Levicki
