I guess It should be something like this:

//ad.domain/ns is so called DFS root.
Domain based DFS root is hosted on a primary domain controller and replicated
to backup domain controller.
So 'ad.domain' should be resolved to one of domain controllers and a domain
controller should host share 'ns'.
In case when ad.domain resolved to a backup domain controller, it may respond
on tree connect with PATH_UNCOVERED error and client should ask it for referrals.
