I much need help my company to design the AD.
My company will have host own E-Mail Server soon by using MS Exchange Server 2007 Std. (Only one Server deploy in the DMZ zone, it is mean that no edge Server on DMZ)
And the E-Mail Server have a public Domain Name, like xxxx.com
And our LAN have over 40 PC.
Now I am wonder the LAN AD Design part.
Using xxxx.com or xxxx.local is best? (Where the xxxx is same as the Public DNS we apply already)
Reason is why and on the future, if my company have more money, the E-Mail Server maybe have the Edge Server add to the DMZ and the old server will change to place in the LAN ...
So, I am feeling a bit confused on MS Exchange, since I am new on it, if using xxxx.local, how it service the Public user, if later place it in the LAN?
