Check MAC Address before create Teaming
I found a strange problem with a host WS2012R2 (HP Proliant DL 380 g9 with 1 NIC 4 ports) during Teaming creation. For an astral reason, when I create a team, Windows assign the same MAC Address to Team NIC and also to Hyper-V Virtual Switch; the result is the total fail of everything.
Why Windows Server 2012 R2 hasn’t a pre-check task to understand both NIC have the same MAC Address? Much better is check the MAC Address of the entire host.
