Is your lan connected to any other networks offsite. If it is we have had simular problems from other sites replicating from a corupted database. We would have to rereplicate to resovle the problem. We also had the problem that we ran out of ip addressesand the DHCP began issuing numbers that were already in use.

Ok here is my suggestion... Are your routers setup to allow bcast to pass through. If so then you could be getting conflicting data from another domain..etc. Also I have noticed if you set the Lease past 90 days DHCP sometimes has a problem releasing the computer from its IP even when Computer using that IP address releases it. The way to verify this is to use some Network Monitoring tool If you have SMS then you can run in promiscuous mode and capture all packets from DHCP. This will tell youwhere theconflict is coming from...IE across the router or such....I hope this helps out..This is how I determined what my problem was.. I changed the lease date to 90days and bam no more problems....
