Hi Brian!

I'm not going to be too much help, but we used to have a AVII that was very
sensitive to firewall changes and linux updates. I can't recall the
software/process that would 'break' but often after an update it would no
longer automatically launch upon reboot essentially breaking any possibility
of communication between the workstation and the console. There used to be
a wizard at Bruker, Peter DeMue (Demouo?), who would eventually track it down
and reset the firewall or whatever process it was to get things going again.

IF you are able to communicate via a web browser it may well be that you are
bypassing this process that needs to be running but isn't.

This comms issue manifests with all sorts of downstream errors that really
point you in every direction but the right now.

Was there any kind of background update that might have taken place right
before the trouble began?

I'm going to end up posting this to AMMRL in case it jogs anyones memory....
