I have four Hyper-V virtual machines with Windows Server 2012 R2 and Active Directory set up. They are all in an Internal switch configuration and can communicate with each-other fine.
- AD1 is the first DC created in the forest of "domain.com"
- AD2 is the second DC created in the forest of "domain.com"
- AD3 is a child adding the subdomain of "test" to "domain.com"
- AD4 is a tree "tree.com" added to the forest "domain.com"
In AD1 there is no entry for the "domain" of AD4, while in AD4 you can see it fine.
I was wondering why that could be and how to fix it.
