CumulonimbusHi,
Dns client will not follow cname. It send a request and expect a response including all information required.
The dns forwarder (AD) will request his forwarder or root servers.
If the AD uses a forwarder, it works as a dns client, else, it read response and follow NS, CNAME.. until it receive an error or the expected answer (ex : ip address of the resource)
When it get it, it reply to the dns client.
