AUtomatically clear old dhcp reservations

HI,

Is there anyway to automatically clear old DHCP reservations from a windows 2003 DHCP server?  I've got a scope that gets filled up (and I cant add/modify the scope) regualrly and I need to clear out old reservations.

Many thanks
John

The point of DHCP reservations is to ensure that no other device ever uses that reserved IP; therefore, automatic deletion of IP reservations in DHCP would be contrary to it's reason for being! Reservations can only be deleted manually.

Are you sure you are referring to reservations, and not simply address leases? If it's the leases you are referring to, then the only way of setting the expiration of these leases is by editing the properties of the scope and changing the lease duration.

Sorry, just tro confirm.  I'm talking about leases.

So are you saying that the only way to free up leases no longer used is to reduce the lease time?

Thanks

Yes, or right-click on the lease or leases and select delete; if you have access to the DHCP server.
