• Each DC has just one IP address and one network adapter is enabled (disable unused NICs).
• IPv6 should not be disabled on DC’s NIC card. Set it to “obtain IPV6 address automatically” and “obtain…

In the event that you’re using UUID or MAC Address to uniquely identify servers in the a database (the MDT database for example) you might want a quick and easy way of getting these values from the Command Prompt on the target server/client…
