At this step, you can specify the fully qualified domain name of the virtual machine.
To specify the domain name of the virtual machine:
First make sure that the DNS server has an A record for the specified domain name and that the domain name matches the IP address that you want to assign to this virtual machine.
If the virtual machine has multiple network adapters and is connected to multiple network segments, use the domain name that corresponds to the network adapter connected to your organization's internal network.
