Is NLB involved at all? DNS RR? What's the problem being solved between TMG2 & EMS? Is it possible that it's exhibiting in a different form for TMG1? From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Jerry Young Sent: Saturday, May 21, 2011 7:14 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] TMG Reboot Connectivity Issue 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. :) -- Cordially yours, Jerry G.
