I have one Domain Fred.com
And the company is merging with another Jane.com
jane.com has lots of domain admins.(which Fred.com can’t trust)
I need to share resources and keep the security that Fred.com has, I’ve read on MS TechNet
"Domain administrators of any domain in the forest have the potential to take ownership and modify any information in the Configuration container of Active Directory. These changes will be available and replicate to all domain controllers in the forest. Therefore, for any domain that is joined to the forest, you must consider that the domain administrator of that domain is trusted as an equal to any other domain administrator."
and this worries me as Fred.com is a secured Domain and although in the future all of jane.com’s users and computers will be migrated to Fred.com I still need to preserve security until Jane.com is removed
What are my options?
