Active Directory is dependent on DNS as a domain controller location mechanism and uses DNS domain naming conventions in the architecture of Active Directory domains.
Then I tried the diagnostic tool link that popped up in the webpage, which showed me DNS Server Not Responding Error.
As a result, DNS is positioned within the discoverability and logical structure components of Active Directory technology components.There are three components in the dependency of Active Directory on DNS: The Windows Server 2003 or later domain controller locator, implemented in the Net Logon service, enables a client to locate a domain controller.The component contains the DNS–compatible and the Windows NT 4.0–compatible locators that provide interoperability in a mixed Windows Server 2003 or later – and Windows NT 4.0–based environment.In past Inside Out columns, I've shown you how to use simple batch files to set up just-installed systems as domain controllers (DCs) and to create disaster-recovery tools.I've also shown you how to use Netsh to configure and fine-tune your IP stack—the first step toward making a Windows Server 2003 or Windows 2000 server ready to ascend to DC status.Prior to disabling Driver Signature Enforcement you may need to Disable UEFI Secure Boot in BIOS. v=5n G4z Mdr HKs The following video explains how to disable Driver Signature Enforcement on Windows 10: https://
