All,

I am experiencing this now and it's peculiar.  Can anyone explain this
behavior?  I'm thinking it's by design but want to understand the reasoning.

I have two array servers, TMG1 and TMG2.  I have a separate Enterprise
Management Server (EMS1) acting as the Configuration Storage Server for both
TMG boxes.

Currently, TMG2 cannot communicate with EMS1.  I know why and should be able
to resolve that soon.  What I don't understand is that in this scenario
where TMG1 and TMG2 can communicate but only TMG1 can communicate with EMS1,
when one of those TMG boxes are rebooted, the other TMG box drops off the
network like it's gone into some kind of blocking mode while it is
rebooting.  When the TMG box that was rebooted comes back up, everything
goes back to being good.

I'd love to understand why. :)
