Chuck,

Errors did not appear on AS400 job log (that we could find, anyway).
Don't know if they showed up at our WinNT server.

'Hard' addressed devices were those 1"x3"x4" HP print servers.
I don't now how address conflicts get handled on NT.

Because of our Sys36 background, devices dropping off-line have always
caused us to look at address problems first.
Printers were historically the most likely culprit.

Poor address assignment practices (some fixed, some dynamic, improper
'pool' settings) on our part seemed to be  the root cause of problems.

I REALLY don't know enough about networking stuff to have any idea about
what should have happened, or make recommendations about addressing.

I do know that when we fixed the address conflicts, the problems went
away and devices quit dropping off line.

Tim

Tim,

In that case shouldn't the "2nd" device requesting this IP address have
gotten the "IP address already in use" message ?

Dave,

We had this (at least similar) situation here. Seemed to be caused by
duplicate IP addresses. System would 'soft-assign' an IP address to a
device, then another device with the same address that had been
'hard-assigned' would be powered on and devices would start erroring
out. This may not be a technically exact description of our problem, but
sounds similar, and might give you somewhere to look.

Tim
