Hello all.
I've been reading The DHCP Handbook by Ralph Droms & Ted Lemon. In
it, they describe a behavior of the DHCP client for Windows 95 and 98
that is less than desirable (why am I not surprised?).
Specifically, on page 291 and on page 308, they state that the MS
DHCP client does not use any new options (like a new DNS server
address) when it renews its lease (or when the machine is rebooted).
How are people dealing with this? They state that the only recourse
is to run winipcfg on each client and force them to release the
leases.
There is also mention of a feature in v3.1 of ISC DHCP server that
will allow setting of a flag on a lease making the server send a
DHCPNAK to renewal requests of that lease. Is this enough to force
the MS client to update its options? How long does the server keep
sending DHCPNAKs? Does it just send one and then terminate the lease,
or does there need to be more intelligence involved?
Since Windows is the predominant platform on ResNets, this is a
significant issue, n'est-ce pas?
Thanks for any advice you care to share.
