When the DHCP service is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service this error will be shown in the System Event Log,

Microsoft strongly recommends the use of DNSCredentials when you are running the DHCP Server service and DNS services on the same domain controller to ensure the integrity of Secure Dynamic Updates.

Simply create a new user (non domain admin) and add it to the DHCP server configuration in order to authenticate the dynamic updates

To view the current configuration:

netsh dhcp server show dnscredentials

To set a new configuration

netsh dhcp server set dnscredentials UserID Password

GUI:

  • Start → Administrative Tools →  DHCP.
  • Under server → Right-click the IPv4 or IPv6 → Select Properties.
