I have a child domain I am trying to demote and remove as we are no longer using it. Just unclear about the forest trust. Our main domain dc.com has a child domain secondary.dc.com that I want to decommission. Now im happy with the dcpromo part just not the transitive trust part.
So.....When I tick this is the last domain controller in the domain, will this also remove the AD domains and trusts between the primary and secondary domain?
If it doesn't how do I go about this as currently the remove button is greyed out because it is a child domain
thanks :-)
