    I have 3 domains that are all their own separate forests:  

    sample.domain.com

    first.sample.domain.com

    second.sample.domain.com

    They look contiguous and like sample.domain.com is the forest root, but they are actually totally separate.  I cannot create a forest trust between them.  is this because their names are the same?

    When a name suffix in a forest conflicts with a new forest trust partner or when a name suffix in an existing forest trust conflicts with a new forest trust partner, the name will be disabled in the new trust. For example, a conflict will occur if one forest is named widgets.com and the second forest is named sales.widgets.com. Please read the below KB.

    Thank you so much for the info and the tech note.  This helps.  So, I SHOULD be able to create the trust as long as everything (i.e. DNS resolution, routing) is fine, correct?
