I have a Windows 2012 standard server and one windows 2008 server running on vSphere ESXi 5.1
Both are domain controllers in different domains.
I have set up a trust relationship between the 2 domains.
This seems to work just fine, but now and then the trust disappear on one side.
If I open "Domains and trusts" on both DCs, I see that the trust is valid on one DC, but on the other DC its gone.
It does not help to reboot the 2 DCs.
To fix the problem, I have to remove the remaining side of the trust...and then re-establish a new trust. Then it works again.
Some times the trust is there for one month.....sometimes its gone after a week.
What is happening.
