I see what Jeremy did with the domain names / server names in Figure 1.6. (Example.com was a placeholder...)
Chap 1, pg 21: "There are two domains: Example.com and Widgets.Example.com...One DC, named EXAMPLEDC1...other Domain Controller, EXAMPLEDC2...".
However, in Figure 1.6 on pg 22 which depicts the above mentioned narrative, the domains are named Corp.com and Widgets.Corp.com and the DCs are CORPDC1 and CORPDC2.
