Hello
I have a Parent / Child domain structure in production. I removed half
of the mirrored drive set from each of a parent, and a child domain
Controller, and installed them into other servers of the same type in a POC
Lab environment.
Once the two domain controllers appeared to be functioning properly, I
DCPROMO'd up both a new Child DC, and a new Parent DC. Once they appeared to
be functioning properly, I DCPROMO'd down the two original domain controllers
that I had imported from production. I had to create some manual
Replication Connections to get things going, but other than that, things
seemed to be functioning OK
Everything seemed fine for almost a week, or more, and then I started
noticing that I was getting some strange behaviour from DNS.Name resolution
started failing in completely inexplicable ways.
After looking into things more closely, I realized that the parent
domain has been deleting itself from Active Directory!!! I have event log
messages saying that the parent partition was successfully been deleted from
the Directory. When I run Repadmin /showreps, I can see that the Parent
Partition has dissappeared from all of the child Domain Controllers, and is
only running in a dinished state on the the parent itself. I can still log
into the Parent Domain, but I suspect that by tomorrow, the may cease to be
available completely.
The only remaining Parent DC says on the surface that it is a member of
the Parent Domain, but under the surface the tools are telling me that it
actually thinks it is a member of the Child Domain!!
Has anyone ever seen anything like this happen before??? If yes,
please help!!!
Thanks in advance
Steve
