You could:
1. Walk to each machine and release the lease it has and force it to
DISCOVER the new changes
2. If they are indeed short lease times, you could shut down the dhcp
server for the amount of time it takes for the leases to expire and
restart it for the clients to DISCOVER the new changes
3. Configure out the old settings so the server will NAK a RENEW request
from the client, and force it to DISCOVER the new settings
4. Delete the clients entry from the dhcpd.leases database so the server
will NAK a RENEW and force the client to DISCOVER the new settings
There may be more ways. Basically, as long as the old lease options and
addresses are still valid, the server will continue to RENEW those
clients. Each one of the above possibilities should be approached with
a certain amount of consideration and possible fault analysis (ie what
could go wrong if I do this?) except maybe the first one which is
probably the least desirable.
I'm sure others will probably have some fine suggestions too.
Cheers,
Matthew
