I have a 2012 guest server on a VMWare 5.5 host server that works fine, but one nic (E1000) will randomly stop passing traffic; usually after a day or two. Disabling and re-enabling the nic brings it back to life. This only happens on one of the two nics.
The 2nd nic is on a management vlan and does not have a gateway, but always is available.
Any ideas what would cause this and how to fix?
