I was returing to an older snapshot of my Exchange servers. But when i want to logon to the Exchange server, it came with “Trust relationship has been lost with domain controller”.

Normally you just rejoin the domain, but this is not a good idea, when there is installed Exchange services on it.

I fix this with netdom.
Logon to the Exchange with a locally logon account.
Start command with Administrator rights
Type: netdom /RESETPWD /server:DOMAINCONTROLLER /UserD:DOMAINNAME\ACCOUNTNAME /PasswordD:PASSWORD OR *
