experiencing a problem last days when our Domain Controller becomes inaccessible by Domain Computers.
It happens once a week and when we restart an external Cisco switch that is conneced to the server, everything becomes normal.
The same switch is used by other computers and they normally work but DC server, which is a VM hosted
on a Hyper-V Core Server, stops working with no reason. The Hyper-V Core Server host is also accessible without problem,
connected to the same switch.
So, we think that the switch is not a problem, it could be something on the DC virtual machine that is cleaned up by restarting the switch,
i.e by resetting the host or VM network adapters. In Event Log on the DC virtual machine and in the Event Log of the Core Hyper-V server
we can not find anything related to the problem. Both, DC and Hyper-V Core server are running windows 2016 Server OS.
Please can you advice me about what could cause behavior like this?
