My customer has a small office network with a hyper 2019 running 2VM's - 1 DC and 1 app server.
The hyperv host has been joined to the domain. The problem is that when the DC is switch off we cannot log into the host server
as a domain user. (local accounts still work) It reports that there is no authentication server.
We have this configuration on several sites and there is never an issue logging into the host when the DC is off.
In fact this customer has just migrated from a 2012r2 host that was running the same 2 VM's and domain users could always
log into the host regardless of whether the DC was on or off.
