|What's to analyze? Either:|
1. You have static addresses and have duplicated one.
2. You have mixed static and dynamic addresses and the zone on your DHCP server also covers the addresses that you have statically assigned.
3. You have more than one DHCP server with overlapping zones.
It should be trivial to determine which one is the culprit. If you still can't trace it then switch everything off, boot your DHCP server, then turn on your devices one at a time. Look for an error message.
