I am currently experiencing an issue with one of my clients.  Each time they lose power I am forced to power their units up manually since they do not have an active WOL setup.   After I log into the servers after bringing the DC/ FS back up I noticed that no one is able to get any internal connectivity to the network or internet.   The only way I am able to restore internet/ local lan connectivity is to flush the DNS cache, re-register the DNS cache reboot the DC and then everything is restored.


Windows Server 2016 Standard
NIC - Embedded LOM 1 on Port 1
DNS set to 127.0.0.1
Secondary 8.8.8.8

Not sure what else to include this is a class c network with only 3 servers a couple of managed switches and 1 ASA.
