i'm looking at a windows 7 client that is not happy with dhcp.  i know this machine had
been happy dhcp'ing on the network 18 months ago, but now it's not.  here's the symptom:

lilly Jul 31 05:57:38 Ack(10.1.1.1-10.1.1.11)id(id016480993af534)ci(0.0.0.0)gi(0.0.0.0)yi(10.1.1.11)si(10.1.1.1) typ(5)leas(1800)sid(10.1.1.1)mask(/112)router(10.1.10.1)host(thinkpad.quanstro.net)dom(quanstro.net) dns(10.1.1.1)NBtype(2)
lilly Jul 31 05:57:38 Decline(0.0.0.0->10.1.1.1) xid(e52418a9)flag(0)ea(6480993af534)ci(10.1.1.11)ip(10.1.1.11)id(id016480993af534)sid(10.1.1.1)need()

it appears to ask for
	mask dom router dns NBns NBtype NBscope discoverrouter staticroutes 121 249
121 is classless static routes

it's not clear to me why the win 7 machine is declining the address.  has anyone seen this before?

looks like the problem was a prior config having given another device the same ip. the client is not giving up its address even after lease expiration.
