Hi everyone
Last week a strange thing happened.
We have a 3Node ESXi cluster, with a lot of virtual machine on it
For an uknown reason, one of the node had a problem on the management network (suddenly stopped responding to ping and got disconnected from VCenter): the virtual machine hosted on this node kept working with no problem, but I wasn't able to reconnect the node to the VCenter using the vSphere "connect" command.
So I had to connect a keyboard to the server, and restart the management network. Everything is back to work except 4 VM, that still don't respond to ping and I can't remote desktop connect to them.
I tried disabling the network card inside the OS (which is Windows Server 2008R2) and tried editing the properties of the VM (disabling and re-enabling the network), but nothing worked. I had to move the VM to another node and the VM works flawlessy. If I move the VM back to the problematic node, I still get the problem of the VM not responding to anything on the network
I tried to double check the vSwitch.
Below is the vSwitch (which is the only network attached to the VMs that still have problems)
Any suggestions?
