Heloo to all,
i dont know this
Do i need to set default gateway to users for domain controler autentification or no when they are in same subnet as domain controler except dns?
You only need to set a gateway if you want traffic to be routed. Traffic on the same subnet does not need to be routed.
That said, if you don't set a gateway, it won't be able to communicate outside of the subnet, so your clients using it for DNS won't be able to use it as a recursive resolver.
