I wanted to retire our old Windows 2003 server witch along with file shares was also our Exchange 2003 Server and held our mailbox database.
Once I had installed a fresh copy of Microsoft Windows Server 2008 R2 on to the new box I installed AD DS and promoted it to Domain Controller holding the Global Catalogue (GC), I went ahead and transferred all of the FISMO roles without issue. I then restored all of the data from the old server on to the new one.
I then installed Microsoft Exchange 2010 from scratch got it working and tested, then I transferred the mailboxes. Once they had completed I tested it further and disabled all Microsoft Exchange 2003 services on the old server. Everything continued to work well.
After 48 Hours I decided to complete the retirement of the old server as the new box was handling everything without issue. I ran DCPROMO on the old server and DC PROMOED it out.
The next time I opened the Microsoft Exchange EMC I see the message as shown in the attached image each time I open EMC. Many of the Microsoft Exchange Services including the information Store now also refuse to start on the new server.
Any ideas would be gratefully received. Thanks in Advance!
