Hi ALL, I need to configure a DHCP running on Cisco switch or MS2003
with lease option of 30 minutes so that when the client starts lease
renewal they will get a new ip address instead of keeping the old ip
address. This needs to be done on the DHCP server side and not in the
client side.

All I've ever been able to do is change the pool such that the old
addresses are no longer valid leases. In other words, say your current
pool is 100-200. If you change it so that the new pool is 2-99, then
when the client tries to renew the address is no longer valid, so it
gets a different lease.

I switched to ISC dhcpd because the Windows based ones don't seem to
have nearly as many features, and the features that exist don't seem to
work in a predictable fashion.
