Julie,

The only real way to solve this problem is to make sure that your pools 
don't include already issued static addresses. The usual way to do this 
is to have part of the network reserved for statics, and start the pool 
outside of that range. If you have existing static addresses scattered 
throughout the network that cannot be changed for some reason you can 
create lots of little pools that are split around those static 
addresses. The other possible solution is to create DHCP reservations 
for the already-assigned static addresses, but that doesn't really solve 
your management problem long-term.

Unfortunately, there is no "easy" solution to this problem, your 
organization needs to be a little more proactive in your network 
management.

hope this helps,

Doug
