Hi,

Have you enable Allow in Filters?

By enabling the allow list, you automatically deny access to the DHCP server addresses to any client computer not on the list. Try to disable Allow(Filters-right click Allow-Disable) and check to see if it works.

Hi Sakthivel,

Can you try restarting DHCP server service and see if it helps? Check in event log and post us the unedited log related to DHCP.

Thanks,
