Hi guys,
I've noticed a strange issue from the ESXi phisical console: if I want to test the management network in a fresh installation, I logon to the console, go to the "Test Management Network" and filling up the 4 fields (usually ping gw, dns1 dns2 and lookup for the host name). If all is right, I'll have 4 ok. But if I repeat the test, the name resolution go failed. Restarting the mgmt network, still have name resolution failed. Rebooting the host will reset the error only for the very first time, the second one will fail...
This is not a big problem, but it is very boring in a production environment if you have to troubleshooting some connections problem...
