We recently started receiving messages in the event log of the PDC at our main location stating “The DHCP server issued a NACK to the client for address 10._____ request ______. However, I am unable to locate that IP address on the network to see what device is causing this. I am assuming the 10.__.__.__ address is a local network address, however, it also appeared on another of our LANs that isn’t connected to our main location. We all use the same data processor, but I do not know why a 10.__.__ address would be attempting to get an address from DHCP.
First of all, any possible explanation to this, and second, how would I temporarily exclude this address so Event log wont get filled up with these messages (approx. every 2 minutes there is an entry). Since that address is not in the scope I cannot exclude it. I think there may be a way to add the station so this wont happen, although I am unsure how to do it.
Thanks,
