[OpenIndiana-discuss] Static IP problem

[Jonathan Adams]

DHCP address was not made unusable, when that does happen (it has happened,
when rebooting a machine sometimes it gets an echo from one of the
switches, now replaced, that lead it to think that the ip was taken) it was
just handed another address.

In the case of this server, it got a response with an address but didn't
use it, just set the address to 0.0.0.0 ... this is the same Solaris DHCP
server that has worked non-stop since we moved into the building ~7 years
ago

We have had problems in the past at another site, with Windows PC's on the
Solaris DHCP server (we put it down to the wiring, but it could be
anything) that PC's running Windows XP and Microsoft office, at the point
in time that the lease is renegotiated would reconnect to the samba server
without first disconnecting, causing the document to deny writing because
it was already open for editing, and automatically closing ... in that case
setting static IP was the easiest solution.
