A very quick question really. I'm currently studying for my Active Directory exam and am a little confused with relation to how DNS Delegation works - mainly in this example.
I have two domains in a forest - contoso.com and nwtraders.com
In the Contoso DNS there is a FLZ with a delegation pointing at NWtraders so that anyone in the Contoso zone can resolve NWtraders DNS queries. Which is fine and makes perfect sense to me.
The question is - is the delegation two ways, since how can NWTraders computers and users resolve Contoso IP addresses and host names, there is no entry in NWTraders DNS which forwards or points to Contoso in anyway?
