DHCP 服務偵測到它正在 DC 上執行，並且沒有設定給由 DHCP 服務所初始的動態 DNS 登錄使用的認證。這不是建議採用的安全性設定。您可以使用命令列 "netsh dhcp server set dnscredentials" 或透過系統管理工具，來設定動態 DNS 登錄的認證。

The DHCP service has detected that it is running on a DC 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.
