Tried multiple switches?  Remember, software things don't just up and 
die.  Presuming you didn't reboot the dhcp / dns server, or make some 
setting that you're not realizing, the software parts haven't changed 
themselves (1).

So that brings us to the most likely problem being a hardware failure, 
or an unrecorded change.  Check the uptime on those machines in question 
(dhcp, dns, etc), and also check the remaining parts of the hardware you 
may have neglected (such as the switch) for both hardware problems or 
potential config changes.

Best of luck, let us know what you find,

1) Time is the one thing that has changed, but the only canonical 
example of this being a problem would be something like the y2k bug.  
*Usually*, time passing isn't going to affect your software 
configurations either.
