The DHCP server offered a lease but the client didn't take it. The two most likely causes are that either the DHCP interval timed out just in time for the server to process the request for the client, but for the client to already have given up, or for another DHCP server being faster and serving the client first.

How do you get it to stop if it's constantly sending that message and always the same MAC?

Don't allow that client on your network. This isn't a problem with the server, the server is doing what it's supposed to.

SOLVED.
Not sure how to do code so someone else can translate if they like but here's what worked for me:
IP --> DHCP Server --> Leases --> Add new --> General="Pool_Name", MAC Address="MAC address of desired blocked", Server="Name of DHCP Server failing", Block access = yes, Address List = Black-list
Hope that helps someone else
