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

Oli

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.
