unwanted DHCP Reservation

Hi all,

I have several Reservations which I wanna get rid of and just let the Clients get an IP of the 'normal' scope. But: After removing the Reservations the Clients still get their 'old' IP, which isn't reserved anymore.

Further, I tried the following:
-Restart DHCP Server
-Remove the Lease on DHCP Server (3 days) -> a renew of the IP will get again a 3 days Lease
-Remove DNS Entries (incl. Reverse) on a Test Machine (which also has the same Problem with a 'invisible' Reservation)

Any suggestion?
Thx in advance

Is the address within the scope of dynamic addresses?  If so they will ask for the same address again as part of the normal renew/request process.   Easy fix is reserve the same address with a different (random if you like) mac address, wait for clients to get new IP then remove the reservation.
