I just demoted a DC peacefully with DCPROMO, and now only have one domain controller and one Exchange Server. The DC is also a GC. The Exchange Server is pointing to the DC for DNS. The Exchange Information Store will not mount and services will not start. I ran dcdiag and everything passes.
In the event log there are many errors regarding Active Directory. Can anyone help me in figuring out why the Exchange is not starting?
Thanks in advance.
