good morning

i have 4 virtual machine ( all windows server) installed into esxi 5.0.0.469512

sometimes ( about once a month) some virtual machine in no longer reachable ( i cant ping it)

when i have this problem i can't reach esxi host ( i can't ping host ip and i can't use vsphere

but strangely i can reach and use other virtual machine inside

so i can restart host from console

server where i have problem is Power edge t410

i have run the main test ( change ethernet cable , change switch port)

can be a problem of my version ?

thanks Alberto
