Local firewall ahs been disabled to eliminate this option (same issue with firewall off)
We have performed flush DNS on the server

Are there any firewalls between the Exch Servers and DCs? When did this start? Was it working before?

How did you solve this issue ????
Reboot the servers? I hate that suggestion, but unless some patch or change was made, maybe that is all is needed?
Hi Andy,
Domain Trust has been restored by suing the Reset-ComputerMachinePassword -Server -Credential command
Reboot was performed still the same issue (no incoming emails)
Not all service are up
Event viewer show the following errors: (somehow it point to historical site "Jedburgh"

Hi Andy,
No Firewalls between the Exchange and DCs (Both devices are on the same LAN in data centre)
Yes it was working before, They issue started at some point this morning.
It looks like Exchange lost domain trust (only local account works)
We have performed update to the schema from exchange server to AD, but it failed. (it was yesterday evening)
