In our current AD forest we have an empty root domain (UK.COM and two child domains (A.UK.COM and B.UK.COM
We need to separate one of the child domains (B.UK.COM) as it is no longer part of the business.
1. What will happen if we just sever the link from UK.COM to B.UK.COM?
2. How long will B.UK.COM function without access to UK.COM.
3. Is it possible to separate B.UK.COM without migrating everything to a new domain
4. Anything else that would be helpful in the situation?
