I'm having a strange problem that I'm fairly certain is due to
DHCP, but haven't gotten much helpful info from that direction, so
I"m inquiring here.

I'm using netreg 1.2 with dhcpv3 (that's the latest non-test, from Oct 2).
I've had a couple of clients, after registering with netreg, that
can't renew their leases. dhcp gives a "lease unavailable" error
and then NAKs the request. This happened the first time that these
clients tried to renew. After about an hour of NAKs, the client does
a new DHCPDISCOVER, at which point it's given a lease from the unknown
client range. This means at some point the host declaration has been
removed, and i know i didn't do it. :)

So I'm trying to see if anybody else has seen this behavior (didn't
see anything in the archives). According to the DHCP folks, this
problem was fixed in DHCP3.0.1rc8, but there are other problems with
it, so that's no good for a production system.

And I"m using the refresh-dhcpdconf.pl contributed by Steve Hideg,
which doesn't appear to have the capability of making this type
of change.

TIA. chris
