attempt to renew its lease with the server that issued it by sending a request
to the IP address of that server. This starts when the lease is 50% of the way
to its expiration. If it can't find the server, it will try again at regular
intervals until 87.5% of its lease has expired. *Then* it will start
broadcasting to find any DHCP server that can renew it's lease. At that point,
it should find your newly addressed DHCP server.
Aside from a little extra traffic while your clients go through the 50-87.5%
phase, there should not be any problems, especially if your users restart their
