Correct.  The really big pisser that I discovered recently is that while 
the 2 boxen can both handle directory request you still have a single 
point of failure.  This thing called the "global catalog" is in the 
first domain controller and if you want to take that box down you have 
to migrate the Global Catalog.  I'm not sure how bad it is when the DC 
dies and takes the Global Catalog with it but I know Exchange will quit 
working for one thing.
