Your backup system should be able to issue wake-on-LAN requests to wake up
a PC, back it up, then let it go back to sleep. Even my Windows Home
Server which is based on Windows Server 2003 can do that.

You may also find that performance problem being not only backup running
but the periodic full system AV scan running at the same time. A non-SSD
can't keep up.

Backup just kicked in. Fixing that with Remote Desktop.

Unless the DHCP server is misconfigured. The norm is to auto-renew an
address' lease. Say the lease time is 24 hours. When the 24 hours is up,
does the address lease expire (causing a new address to be assigned) or
does it auto-renew for another lease period (another 24 hours)? I've
never
seen an environment where the lease doesn't auto-renew.

Tell the network person to pay the electric bill if they thinks its
reasonable to leave devices on 24/7.

One other thought: Are the PCs built from an image? If so, are they
being
set up with identical MAC addresses? To track which machines have what IP
addresses the DHCP server maps IPs to MAC addresses so duplicate MACs
might
cause random issues with DHCP services.

Wireless laptops exist here. However, most of the computers I have
dealt with are still wired. Our network person has decreed that all
computers be left on at all times. What I could guess is that a new
DHCP lease could get assigned at 8:20 AM, while somebody was connected
to the i and working well from 7:50AM. Suddenly, a dead connection.
This morning alone, there have been three. User can't reconnect, as
that session is "in use" all because the IP address changed. End the
orphan job, potentially reset the device, and all is well.

Guess what I am wondering is how other systems handle this so that
users are unaware of the IP address switch, and if the i has a way to
deal with this. We are terminal at v5r4.

You sure they aren't using wireless laptops and roaming through dead

I haven't checked the countdown clock this morning. Probably 28 days
left. So, this isn't critical.

Corporate mandated switching from static addressing to DHCP. We get
random calls where a 5250 session cannot sign on or just quits
working. The corporate help desk has decided that if they receive two
such calls, then the i just HAS to be down - despite the fact that we
have several hundred attached and functioning workstations.

Anyway, here is my question: If a DHCP connection is established with
the i, and then the lease on the workstation IP address expires, and a
different IP address is subsequently assigned to the workstation
(sorry for the wordiness). is there any way that the i can determine
that address for that session has changed and do something about it?

I know the device description has the IP in it when a connection is
established. But, what happens when that address changes?


BTW, when corporate office sends out a bogus "system down" task, they
are done - task has been assigned. We get the heat for taking "too
long" to resolve the issue.
