Exchange server 2010 "Security database on the server does not have computer account for this workstation"

Client called saying their Outlook was asking for a password to login to Exchange server.
I remoted in and looked and then logged into Exchange server and when I attempt  to login to it I get this message
"Security database on the server does not have computer account for this workstation trust relationship"
Since this is an Exchange server I'm treading carefully. I can login on the local server, just not using domain credentials. Normally I would just unjoin and rejoin, but since this is Exchange I felt I shouldn't do that.
Really out of my depth here, seeking assistance

I think your exchange loss connection with Domain controller. Could restart the exchange server? log on using local administrator then reboot the server?

suriyaehnop - Since the Exchange is a hyper-V I just remove the LAN connection and logged in with the cache credentials, but have rebooted it 2 times with still the same message. The DC shows the server in AD, but acts like it has been reset or something.

Steven Wells - Time is correct and the DNS setting are still the same, point to the only DC in the organization.

you should be able to safely rejoin exchange server back to domain.

Steven Wells - I might be a little foggy this AM, but if I unjoin and rejoin won't there be an issue with the server name already existing on the DC??

no,  the dc will allow you to rejoin if you leave computer object,  and you have full domain admins rights.
