One of the folks in the office saw this message today:

“IP address conflict. Another computer on this network has the same IP address as this computer.”  

I checked DHCP, and sure enough, every single IP was issued today.  I have a /24 network, and I'm out of IPs.  Over the last 2 years I've reduced the DHCP lease duration from 5 days to 4, to 3, to 2, and now I'm down to 1.  

The obvious fix seems to be to change the subnet mask on the network.  (I'm thinking of going with /16).  The effort required to do so, however, would be considerable.  

Anyone have any clever workarounds?  Or, do I need to bite the bullet and change the subnet mask?
