VM occasionally unreachable / unpingable from outside network
Posted on 2013-01-31
We have 2 VMs sitting on different ESXi hosts which occasionally
became unpingable from another subnet/VLAN, giving either
"Request timed out" or "Destination Host Unreachable"
What troubleshooting scripts would you put in place & isolation
measures you would perform?
I've heard of cases where Win 2008 would lose its default gateway
& by a certain value in the registry, it solves the problem. I've
also come across a case of a Win 2008 IP address 'disappeared'
but after rebooting, it's Ok but not sure if this is the case we're
I was told by my colleague who is at the site (where the ESX hosts
are located) that usually the VMs self recovers & became pingable
(& could be rdp'ed in ) again after a while
