win2012 "autoconfiguration ipv4" on NIC with static address

Hi, on windows 2012 server (VM, on ESXi 5.5) , with 2 NICs, we are getting some times an "autoconfiguration ipv4" address, even though the NIC has a static IP assigned to it. It's a VMXNet3 adaptor.

I cant find out why this happens?

I would try re-configuring VMXNet 3 again. Perhaps delete it and re-create it.

Is there a Network Editor on ESX ?  There is in VMware Workstation. Sometimes resetting the VMware Network helps.

It's happening on several VMs, and it goes away after a reboot. It seems like an OS related issue, not something on the virtual infrastructure layer. I see quite a few threads about this when googling, but no resolution unfortunately!

I am not why several machines would all have the same issue. Try a TCP/IP reset and DNS Flush on a machine to see if this fixes anything.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Nope didn't help. it's fixed after a reboot but I need to find the root cause for this.

Did you try resetting (delete, re-create) VMXnet3 ?

I have not seen an issue where a bunch of machines would all fail the same way like this. I don't think QOS would cause an IP failure.

Also look at the host machine NIC's . Maybe they need new drivers or possibly replacing.  Are the NIC's interfering with each other?
