Use VMXNET3.  I have seen the exact same problem more times than I can count.

I know the e1000 family is listed as supported for 2012 but it never works.  Well it usually works for a while then stops.

Hi Tedg,

I have some another Windows 2012 VMs with E1000 NIC, but they never have this problem. So i just confused it is related with E1000 and window2012 or other issue.

Regards,

Simon

Sorry I don't have the exact "why" or "where" for it.

I have just encountered it many times and thought I would mention how we resolve it each time.

Some more info.

Adapter Compatibility.

Another reason not to use it if you are using the listed versions of ESXi.
