VMWare ESXi 5.5 Disconnecting VM from Network

I am running a VMWare ESXi 5.5 2068190 build server with a 2012 R2 VM.  For some reason at random but about once a day now.  It will disconnect the VM from the network.  I can go in and disable the NIC in Windows and re-enable it and it comes back online.

I did some research online and found a couple things to try but nothing has worked so far.

I've never had a problem like this before, so not sure where to start.

The oddest thing I see is it's a Dell R730 with Broadcom NIC's but in Windows it detects as Intel NIC's.

Completely normal, your Guest VM has virtual hardware, and the Host has physical hardware.

The Guest will never detect a broadcom nic.

Now back to your issue, you should always use the VMXNET3 interface, the Intel E1000 interface should only be used for installation of the OS.

So, replace the interface, with the VMXNET3 interface, and please report back, and make sure you have VMware Tools support, e.g. it's installed.
