I just happen to think about this a little. I understand now that the 
DCs will take care of themselves. Currently, though, the shares are on 
the DC machines also. Am I correct in thinking we'll need a way of 
synchronizing this data in the shares?

As we learn more about all of this, it would have been a better decision 
to find a smaller machine to become the DCs and these monsters we're 
using for the all-purpose servers to have been members of the domain 
with just the shares on them. We're still having problems with members, 
so maybe not.

What type of loads do DCs encounter by just being a DC? Let's say we 
have 250 users and each of those may have 10 shares mapped to drives. I 
can see where share servers might experience a fair amount of work 
providing those shares. What kind of work load would a separate DC 
experience doing it's part of the process?
