Event ID: 1037 Source: DhcpServer

Source
Level
Description
The DHCP service has started to clean up the database.
Comments
 
This event occurs when the DHCP server cleans up the address lease database. It will try to free up addresses that are beyond the lease expiration time (e.g. 48 hours) and return them to a state where they can be used by other computers on the network, or the same computer should it try to login and the address hasn't been taken. The Event Viewer will then log the 2 messages 1037 and 1038
You can disable Audit logging on the DHCP server but this will NOT prevent the messages appearing in the Event Viewer. I have not seen anywhere a way to stop this.
