We have Exchange 2013 Virtualized on a Separate VM from our FS/DC and after doing Windows updates today, the Servers came back up just fine, but Exchange would not run. OWA just gives us the login screen but says bad username or password.
When we log into the Exchange VM with the Domain Administrator, it says that "The Trust relationship between this workstation and the primary domain failed."
Outlook on the workstations does not connect, thinking the users cannot authenticate.
How can I re establish the trust without rejoining the domain??
Any Suggestions or help would be appreciated!
