I'm having an issue with one of my ESX servers boxes.
I have upgraded the NICs on one server and I want to add additional NIC to the LAN Switch for redundancy.
I added the NIC successfully, but as soon as plug the LAN cable to it, I will lose the connection connections and when I ping the server I get request timed out. I have to go and physically unplug the LAN cable out of the second NIC that I added to make it work.
I don't have any vlans or subnets so I can say it's conflicting
Any Idea why this is happening???
