Dhcp Reservation Limitations In Windows 2008 R2

Reservation: 192.168.1.101 Consider the following scenario: The reservation for 192.168.1.101 may fail. The error message that will be displayed is: “The specified DHCP client is not a reserved client” The Windows 2008 R2 DHCP Server won’t allow reservations to fall outside of the configured address pool. To resolve this issue, expand the address pool to cover the entire subnet. If you do not want the DHCP server to assign addresses in a portion of the address pool, create an exclusion range. DHCP Reservations can be created even if they fall within an exclusion range. The new scope for this example should look like this: Reservation: 192.168.1.101 Alternatively, you could install a hotfix, that is available on the Microsoft website, to correct this behavior.
