JSI Tip 6946. After you install the DHCP Server service on a Windows Server 2003 domain controller that is running the DNS Server service, the System event log records Event ID 1056?

The Event ID 1056 entry that you receive in response to the subject installation is:

Event Type: Warning
Event Source: DhcpServer
Event ID: 1056
Description: 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.

To resolve this behavior, see tip 6941 - How do I configure DNS Credentials on a Windows Server 2003 DHCP server?
