Before using a new RADIUS server with Active Directory, you must **register it in Active Directory**. This is an important step to ensure that the RADIUS server can properly communicate and authenticate users against the Active Directory database. While other actions like configuring DHCP or adjusting firewall settings may be necessary depending on your network environment, registering the RADIUS server in Active Directory is a critical requirement for operation.
