Problem with Domain Controllers on VMware 6.5
We have two Windows Server 2012 R2 domain controllers that have been running on VMware 6.5 for several months with no issues. They have started to go offline i.e. no network connection, cannot authenticate users, etc. In VMware console VMware tools shows as not running. As soon as we open a console to the servers the VMware tools start and the network comes back. The System event log shows several unusual events such as the system in entering sleep, the system has returned from a low power state, the VMware CAF management agent service entered the stopped state. Has anybody seen anything like this before? I was going to remove and reinstall VMware tools but was concerned this might have an effect on the DC's.

The NIC's are VMXNET 3. We are also thinking it could be a group policy mistakenly affecting DC's or a problem with time synchronisation.
what you mean by no network connection?DC's not responding to ping during these failures

Self fixed.
VMXNET3 is the recommended one, yet E1000E usually comes up as default.
