Event Source: DhcpServer
Event ID: 1056
The DHCP service has detected that it is running on a domain controller and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service. This is not a recommended security configuration. Credentials for Dynamic DNS registrations may be configured using the command line "netsh dhcp server set dnscredentials" or via the DHCP Administrative tool.
By Using the DHCP Server Snap-In
- In the DHCP Server snap-in, which is located in the Administrative Tools folder, right-click the DHCP server that you want to configure, and then click Properties.
- On the Advanced tab, click Credentials.
- Type the username, domain and password of the account under which you want the DHCP Server service to run. You can use any valid existing user account for this, such as a Domain User account. The account should not be set to expire or have any other restrictions.
- Click OK, and then OK again to exit the Properties dialog box.
By Using the Netsh.exe Command Line

ipaddress is the IP address of the DHCP server that you want to configure), and then press ENTER.

You can use any valid existing user account for this, such as a Domain User account. The account should not be set to expire or have any other restrictions.
- Type quit, and then press ENTER to exit.
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. If you do not use DNSCredentials, Microsoft recommends that you run the services on different computers.
