In the past 72 hours two of our servers have lost their trust relationship to the domain.
We are running 2008 R2 in native 2008 R2 mode with our domain.
Both servers were restarted and they regained their trust relationship.
We have poured over event logs, DNS entries, and networking configurations to try and determine why the trust relationship were dropped.
They are both member servers running 2008 R2.
I am concerned it will happen again.
Why are trust relationships dropped in the first place?
