Windows 2012R2 VMhost lost connectivity to network
I installed a Windows 2012R2 server and it has four hosts on it.
Today everything was working fine like the last thirty 30days and the file server lost connectivity to the network. I could log onto the VM through 2012 the domain password work.
I could not ping the gateway nor out the network through the file server.
Clients could not ping the file server.
The other three VM's could ping the gateway and they could ping out side the network.
I re-booted the whole file server and once the the re-boot was complete. I started the file server VM. It came backup and and I could ping the gateway and out side and clients could connect to it again.
The other three came up just fine and work as expected.
Is there a patch that needs to applied to the Windows 2012R for this.
This is a Windows 2012R2 Dell T630 with 96 Gigs of Ram.
Thanks very much for the help!

After getting feedback, this is what I did; called Dell and applied a firmware fix to the the network adapter and BIOS. Software update for network driver on the server. Dell also made a few tweaks to the Hyper2012R2 the network had not dropped since.
I also did a Firmware update to the HP switches they were two version in the wind. I looked at what HP said about the firmware for the switches, but only said it was a bug fix. After I applied that, the switches seemed faster. The network moves better. If anybody else is in this situation look for firmware and software updates that might need to be applied. It maybe too soon to tell if that was the problem, but I am betting it is.
Thanks for the help!
