I had a firewall issue today and caused about a 30 minute outage between
my front end server and my backend server and DC's. When the firewall came
back online my front end server was completely hosed and needed a reboot. I
actually attempted to stop and start services first and even that was unable
to be done. Why would such a drastic failure occur because the firewall was
down for half an hour (or any length of time for that manner)? Does the
front end need constant connection for some reason? If so, why?
