Greetings
I have Active Directory 2003 Setup and Exchange 2007 single server solution.
Recently, I promoted a new Domain Controller on Windows Server 2012 R2. Transferred all FSMO Roles to the new Windows 2012 R2 DC. Both the DC (Windows 2003 and Windows 2012 R2) holds Global Catalog.
I have changed the Configuration DC in Exchange Management Console pointing to new Windows 2012 R2 DC.
The issue is when i shutdown the Old Windows 2003 DC, the Exchange goes down and i see the error in Event logs that Exchange is unable to find the Global Catalog.
Kindly suggest.
Thanks in advance.
