I see what you're saying regarding the laptop. That makes sense for your 
situation (assigning an IP per her MAC address?), because I know it would 
drive her crazy if it were set up with a static IP, and then she couldn't 
figure out why in the hell her laptop couldn't connect to her friend's 
network =).

In the case of servers (as per the original question), servers should *always* 
be set with a static IP so they don't start switching in the middle of the 
night and take down your network. And luckily, they don't move too often 
(some grow legs, but those are rare cases), so their settings shouldn't need 
to be changed that often.
