We have DNS on 2012 server with several zones. One of the zones we added: domain.co.uk is required to resolve several A records internally however, we have a sub domain: abc.domain.co.uk which is hosted by AWS. If our internal users try to access abc.domain.co.uk via a web browser it will result in ‘Page cannot be displayed’ which presumably because it tries to resolve through this zone. If I delete the zone it will work once I flush dns on my machine. So I guess what I am asking what is the method (if any) to force abc.domain.co.uk externally?
