When attempting to add a new DHCP reservation (using a MAC address for a vmware host), I receive the following messages:
"The unique identifier you have entered may not be valid. Do you want to use this identifier anyway?" I click <YES>, then I get
"The DHCP server received a message from a client that is not valid" The only choice here is <OK>. I click this and am brought back to the "New Reservation" dlgbox.
I've been able to add reservations before without any trouble. I have also verified there is no other DHCP server operating on the LAN.
Any ideas here?
