Hi, I'm running a server with ESX 3.5 U2 and four guests. This configuration is running on an IBM HS21 blade server. One of the four guests all the sudden stopped communicating on the network. The other three guests are working properly. I checked the guests configuration and all appears correct. I reinstalled the VMWare tools and rebooted. I went so far as to remove the NIC and add it back in with no luck. It looks like the guest is receiving packets, but nothing is ever transmitted.
At this point since all the guests share the same vswitch and physical NIC, that the problem may lie with the ESX host itself. I was considering at a minimum restarting the 'network' service on the host, or possibly rebooting the server. Do anyone have a better suggestion?
Thanks
