Might try DSRM logon to see what might have happened.

Updated our Server 2016 essentials today and rebooted when it came back to the log in screen there is an X through the network icon on the bottom right and now cannot login. States there is no logon controller available. I have checked the BIOS and the Dell nic configuration says the link is connected. Any help on this? We are dead in the water right now. I have never seen this happen. Any suggestions other than a restore?

2021-10-25T23:21:27.777+00:00 I was able to get in with Safe Mode (networking) but when i go tot the Nic properties it si totally blank. I tried bringing up the update and recovery window to try and roll back but it shuts down after opening. Was hoping to uninstall an update that caused this terrible error. I can ping the server from workstations but thats it. No file brwosing or services seem to be running after it boots to the login screen. Not sure what to do.

This didn't sound like working, but either case if you're now saying it works, try booting normal again. If problem persists then you might try downloading the latest ROM bios, firmware, chipset and driver support packs for the server.

2021-10-26T13:28:08.187+00:00 I tried to use another USB NIC as I do not have PCI cards as a spare. In Safe Mode with Networking the NICs work but there is no protocols listed in the properties window. I see no hardware faults running Dell Diagnostics either and the drive array seems healthy. My last resort is to pull all data off and do a new install of the server using a new domain and then connecting all the workstations to it again. No idea what has happened but down time is going on too long.
