I use them, it's useful on networks where machines only connect sporadically, but you'd still like them to use the same address as last time. A lease isn't a guarantee. A client will usually get the same IP, if possible, but the server can re-use an IP if something else needs it and doesn't have any previously unallocated ones spare. A client can also, still, get assigned the same IP after a lease has expired. Antonio M: <div class="Ih2E3d">> What is different between a Fedora computer and a Windows computer??? </div>See if the DHCP server still stores lease data in /var [1], like it used to back on Fedora Core 4. If so, you'll see that the Windows clients *also* give the server a UID. 1. /var/lib/dhcp/dhcpd.leases -- [tim@localhost ~]$ uname -r 2.6.25.6-55.fc9.i686 <div class="Ih2E3d"> Don't send private replies to my address, the mailbox is ignored.
