I have an ESXi 6.5 server with three VM guests running Windows Server 2008 R2. I have an external switch connected to a router with a gateway of 192.168.25.1, and all VM’s have static IP’s in the .25 network.
All three VM’s could talk to each other and to the Internet with my local DNS servers - until today. Now, each time I ping from one of the servers to any other server and to the gateway I get a General Fault error. I’ve reinstalled the VM Nic card to no avail. I’ve restarted all VM’s and the ESX server and the switch the ESX is connected to, also to no avail. I don’t know what’s changed from when it worked before.
