I have a major problem with Exchange 2007 SP2 running on Windows 2003 R2.
The Exchange 2007 Installation is a VMware 3.5 guest and was done on a DC (Not the operations master). A week ago the VM was corrupted and as a result we restored from a backup of the VM with the unintended consequence of an old System State and causing replication to fail. This is also known as USN rollback.
OWA users are unaffected but Outlook client users can no longer logon.
If I run DC promo on this Exchange 2007 SP2 VM and demote it will it fix the problem or just make things worse?
