This happens very seldom but lately a computer lost the trust relationship with our domain so I wanted to reset the computer credentials. Looking at my main DC (Server 2008 R2) I wasn't able to find that computer anymore.
I am pretty sure that DNS/DHCP have nothing to do with this, I googled many forums that suggested this and I already checked this problem.
My guess would be that this happened because computer was moved shortly after being added to the domain. In my case this means that it was added to the domain on a child-domain controller of ours and moved to the network with our main-domain controller. I can't be sure though.
Is there any way to find out what exactly happened?
Our forest:
Main-DC,
3 Children-DCs that replicate with the main-DC
Already tried DCDIAG, checked LOGs and replication and was not able to find any errors.
Sysprep can't be the problem either, we run sysprep with generalize.
Every idea is much appreciated!
