Hello
Make sure you are reserving your this IP address in the correct scope. I mean check for exclusion and address pool and make sure the address you are trying to reserve in not excluded. Any event related to DHCP server?

Hi,
Please refer the following KB:
The address that you tried to assign to a client is either not in the Internet Protocol (IP) address range for this scope, or the address is already in use.

Hi All,
I have faced the same issue while doing reservation for One IP Addresses with its MAC Address.
Workaround is:
remove colon's (:) in MAC Address.
