The problem is between two machines who are in dynamic pool, no of them in reserved area.

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
