server can't ping default gateway
Posted on 2016-09-06
I have an SBS 2008 server. Randomly it could not ping default gateway/firewall and thus could not get to the internet.... It's happened twice now with completely different fixes which is strange....
reboot server - does not fix
clean up some ip and dns settings, and reinstall tcp stack, reboot, set static IP again - things work
(This makes me suspect something on the server itself)
second time a day later
just move this server from the switch it was plugged into and move it to firewall directly and it works....
(this makes me thing something wrong with switch, but if that is the case, how did the first fix ever work?)
