I'm not sure what is going on but I have been building out a new environment remotely. All the VMs I spin up that start out as 2019 servers in a WORKGROUP seems to respond to RDP requests extremely fast and I see no delay at all. The few servers out of the bunch that I have added to a new domain recently created seem to have a delay that is at least 20 times slower in response to my initial RDP requests before I see the login credentials request.
Any idea why the domain is slowing things down?
